Junk yards and online (eBay, FB marketplace) would be where to source the axles. Problem is finding a car with the right axles. There's 4 or 5 different types of axles. While there's general guidelines you can follow to know which axles will be in which car, it also seems that Fuji just grabbed a random set of axles off the shelf and just put them on each car as it was going down the assembly line. It's really annoying tracking down axles. I had to buy 3 axles that were listed as the axle I needed before I got the one I was looking for. Unless you go there in person and can identify the axles, assume the person who listed the axle (new, refurb, or used) doesn't know which axle it is. In the FSM, there is an axle chart (in section 4 I believe) use that to find the identification bands on the axle shaft, the shape of the inner joint cup, and the inner joint spline count. These are your general identification landmarks. For the interim, I'm sure the Rock Auto axles will work just fine. But once you get the car rolling, I'd be saving up for used OEM axles, new front struts, a set of 4x140 wheels, some wheel bearings, and strut mounts. Just my opinion but if you're even considering dropping the car to stock height, start locating parts ASAP. KYB struts can only be found easily shipped from Australia. So shipping is very expensive, plus the "old a** part" tax. You'd be looking at $700 for a pair including shipping. Strut mounts (again, KYB brand) are also very hard to find. And typically go for $40-$90 per mount. It'd be expensive to drop the car and give the suspension the attention it probably needs or will need soon. But it's easier on the car long-term and makes the parts struggle a little less complicated. Tldr: The Rock Auto axles are a good permanent solution for a "throw away" car but if you plan to keep it long term, I'd recommend going to stock suspension. Begin your hunt for the parts required to make that swap ASAP. Last call for parts was a decade ago, we're stumbling out on the end of a bartender's broom at this point.

The weather was finally somwhat bearable (if humid as hell for my tastes), my leg is 99% healed, and I had a day off to play with, so I started poking at the rear suspension again. Pulled the subframe apart and separated the sheet metal piece from the diff, and removed the knuckle assemblies including the CV's and lateral arms. Also I think i made my first obnoxious mistake. Nothing too unrecoverable but still... annoying. Made a couple of test fits and chalk marks with the whole assembly to get an idea of what I thought I'd be wanting to chop. Actually chopping was the mistake (sort of) - but I'll detail that shortly. The diagonal marks indicate roughly where the frame ends on the brat where I need the subframe to sit. Did another test fit with just the diff and subframe, determined it would be easier to fit where I needed it to if I just cut it straight where the stock bushings ended. The intent here was (and I guess still is) to re-fabricate mounting points to the frame with new bushing locations to fit in the smaller chassis. Got everything tucked up in and sort of leaned in place where I think It will go. The diff is bolted to the subframe, and then also mounted to the original Brat front diff crossmember. Fits pretty close to where it needs to be - only thing now is that it looks as if there's about 1.5 - 2 inches of height I'll need to make up to keep everything sitting level. It was at this point where looking back I think I maybe made a bit of a mistake cutting off the bushings. Funny thing is - mere minutes after completing all the test fitting and cutting today, a friend sent me a youtube video from a guy doing a similar subframe swap in on a later gen brat where he just...*widened the frame and used the stock bushings.* Shocker, this would have been a much simpler approach and I think there would still be enough clearance for me to narrow the links and CVs to tuck everything back in under the stock wheel wells. Granted, the gentleman in question had to refabricate his whole rear frame, and appeared to be planning on adding a widebody kit setup though so maybe he didn't need to be so concerned about the wheelbase width in the back. Lack of access to the "frame" from a different perspective was also a reason for me not thinking of this - I'm still using the bed as a demi-storage locker and haven't cut the bed floor or wheel wells out yet. Might change that and get the ol' death wheel out for the bed soon to, but that metal is in pretty good shape and I'd rather not cut into it if I don't have to. I'm deciding to look at the silver linings here - It's probably for the best I'm still going my own way of it - I'm definitely maximizing the room i have available to move the wheels inboard for a more stock look. I'm thinking I might be able to get clever and integrate the original moustache bar mounts or something... We'll see - I have to sleep on it. Absolute worst case I go to the junkyard and try to source another rear subframe and then widen the frame rails similarly to the other builder. A quick Google looks like one can be had for about $150 used. Maybe less if I find a pick and pull with one nearby or get lucky on marketplace. Mounting problems aside - having put everything roughly where I want it and looking at the bare underside of the subframe itself I think I'm going to have to take a slightly different track and shorten both the CV as well as the lateral links - chopping up the subframe more than I already have is going to prove much more complex than I initially assumed. I'd wanted to try to save on parts money and maintain stock impreza parts wherever possible, but in this case I think it will end up becoming much more expensive in terms of my time to relocate the pivot points instead of just changing to an adjustable link setup (It looks like I can get some of those for my GC model year for about $200.) Hopefully adjustable links will be adjustable enough to where I don't need to modify those to shorten them sufficiently. Anyways, looks a lot like it did when I started today but now I have more information to play with. Ever onward!
