Ok guys, who's done the swap? Jibs is doing it to his brat and we're having some problems bolting the shifter up to the body. We got the EA82 shifter and all, using jerry's kit. There doesnt seem to be any holes in the body to bolt the shifter mount to.

What did you guys come up with?

When I put one in my Brat, the only problem I had was the shifting mechanism - the plate on it - was a bit short, so I had to fab a short extension. Other than that, it went very smoothly. A slight mod to the shifter itself to improve the throw, but that was merely a preference of mine.

The way I've done it is to drop a longish bolt with a large washer through the floor in the tranny tunnel. Then use some spacers (washers, those thick guys from under the alternator mounting plate, etc) to get the shift mechanism level. Has worked fine on the ones I've worked on.

I've done the EA82T and 5 Speed constant AWD into my EA81 Brumby, i have no problem with gear shifters or fitting.. short of drilling one hole to mount the rear rubber mount from the gearbox and elongating the holes in the transmission mounts. The only other issue was the front chassis rails and cross member, just a little mod there really.
I wonder if the 3 inch lift i have ironed some problem out for me?

Cool, so it looks like we gotta drill a hole. No worries, just thought things should bolt up.

Thanks Guys,

So how much longer does the ea81 driveline need to be? I'm tired of waiting for a guy to weld in the plate for the 2 piece driveline.

I'm about to start mine, I'm doing a lot of custom work anyways, so I'm fabbing everything. I'll probably cut out the interferance areas of the tunnel and weld in new pieces.
It'll be nice to drive with intact synchros.
I know for a hatch the driveshaft has to be 46", but I am doing the t-case mod, so I won't be using that. I'm just trying to figure out how much this thing is going to hang under the car, maybe I'll do a higher center stack with cable-operated 4x4 linkage to tuck it basically up between the seats. Just have to relocate the parking brake control.

I too used Jerry's kit, but when mounting the shifter I used an existing stud that was in the transmission tunnel, worked perfectly too.

On the 4WD shifter, I had to create a mount on the inside of the tunnel and drill a pair of holes.

When I did mine, we reused the stock shift linkage, except for adding in the 5 spd shifter itself. It just bolted up in the same spot....IIRC. But we cut and rewelded the linkage so up top it looks completely stock.

perfect because im about to yank a trans today for my 82 hatch to swap in the 5sp d/r

gotta admit it though, this little 82 with the 1.0 4th gear really scoots on the highway.

yep , drilled a hole,cut a piece of 1/2x1/2 tubing to put in there with a long bolt and it worked out fine.beware though,the longer the bolt the more apt you are to have "play" in that mount.short and fat spacer is my vote for the next time i do this,to help with stability at that mount.
i actually had to pull over just before white pass one time due to slop,and realized the nut had loosened considerably,even though it was a nylock!i attributed it tothe mount not being stout enough due to the spacer.
i never had a problem again,but also never changed the mount either.

i will be doing it a little different this time.

and jibs,you can make two little "L" brackets to bolt to your tunnel for the driveshaft.i did it and never had any problems.of course you want to use bullet proof fasteners,but i just measured from side to side to get it as centered as possible and had very little whine or vibration.

as a matter of fact i think i used pieces of an old bedframe.:lol:worked well though.cheers, brian

Yeah JB & I took care of this a couple years ago. I can't remember how we finally did it. But that swap has been done, and even pulled and placed in another brat by now :)

Still some real good info floating around in this thread.

I just picked up a 5spd D/R from upullit so my hatch is getting the conversion...My 3rd gear syncro is shot on the 4spdD/R(as it was when I got the car...) .

I looks like I can reuse my ea81 flywheel until I do the EJ swap.

Spacing of the starter 4/6mm back with washers.
My driveline cut to 48" tube only

Will the clutch cable work ok ?
My ea81 is 36.25" long and the Ea82 is 33.4"

Also is the speedo drive on the Ea81 trans the same as the Ea82 ?

Other than the shift linkage mount is there anything else to modify?

(sounds about right. I think mine was around 53" cap to cap, lengthened)

yes, keep the ea81 cable. the mounts under the dash are different....

Also is the speedo drive on the Ea81 trans the same as the Ea82 ?
Yes, Same.... though the rubber sealing washer is located differently... I think to get the best fit, I removed the rubber washer on mine.... if you have a chance to look at both, you will see the difference... but the ea82 speedo cable should work in yours fine.

Are you using Jerry's kit for the trans mounts? if not, you will need to drill a hole into your ea81 mounts and put them on the ea82 trans....

what's this "Jerry's kit" I keep hearing about? can somebody link me to it?

sounds like I'll need the help of a pro to do the 5-speed swap...

thanks!

Jerry (Bratsrus) makes or used to make a kit that allowed for usage of the ea81 shifters so the interior looks stock, and it allows for use of the better ea82 tranny mounts...

Yeah, I was like "What Brian's helping me put a tranny in my car what?" SWEET!:lol: Yeah I just drilled a hole, used a spacer, and found a bolt. easy enough.

The onlt things to watch for when getting a kit from Jerry - make sure the shift linkages you send him are from an 83+. Apparently they're different than an 82. And make sure you have the flywheel from an 83+ as well, its bigger than an 82's.:)

So whats the deal with the driveshaft? I hear one could put the longer ea82 driveshaft in your ea81 long platform vehicle without modification as long as you mount the carrier bearing. Am I searching wrong?
