You'll have to re-bend the front 2 brake lines coming off of the Master Clyinder. Not a lot, but they will interfer with the Disty if you don't. I just carefully tweeked them by hand. Don't want to kink them.
The Vacuum Advance unit on the disty will hit the M-C, only allowing 1/2 of the slot for timing purposes. This is not an issue on mine. Was told that the M-C for Auto Wagons are shorter than the ones for the Manuals, don't know for sure.
When installing the engine into the vehicle, leave the mounts loose on the engine. This will help you get the studs into the engine cross member. Then you can tighten the mounts to the engine. Before you tighten the stud nuts, make sure that the engine is centered between the frame rails, then tighten the nuts. Not much clearance between cam covers and frame rails, only about 1/4" at the rear.
I have the EA-82 radiator in mine, needs some upper mount re-work to do so. But after comparing the EA-82 & EA-81 radiators, there is not really much difference that I can see. Other than where the cap is actually mounted. Haven't looked at the lower mounting pionts, as they are both in vehicles.
You will need to lenghten the 2 wires for the Disty going to the coil. Am told that the '85-'86 Disty's are the stand alone type. Meaning only 2 wires to hook-up, nothing else. Please use Shrink-wrap and solder on the splices. It will save you head aches down the road.
Use the EA-82 Y-pipe, then whatever you can fit under vehicle for the rest of the exhaust. I fabbed up my own 2" dual system.
Not 100% on which pitching stopper is used right now. Thinking it's the EA-81, have to check on it later, and edit it in.
The person that originally put this engine in, re-worked the gas pedal cable. Not sure that that has to be done. Thinking that one or the other will fit with no problems. I have to change mine out so it works with the Weber better. Plus I can't put my spare tire in now, it stits against the cable, won't allow it to move.
Installing a Weber carb is a whole nother story that is still unfolding. Have hood clearance issues. But I'm working on it.
That's about all I can think of at the moment. Will edit in anything I may remember later.
The EA-81 pitching stopper is used on mine.
You will need to use the EA-81 4 Spd clutch disc and pilot bearing, as well as the 4 Spd's throw-out bearing. Use the EA-82's flywheel and pressure plate.
Above all... Keep the EA-82 flywheel on the engine. Makes doing the T-belts a whole lot easier. The EA-81 flywheel will fit the EA-82 if you drill the mounting holes out bigger. I don't recommend doing that.
Have fun, and enjoy the engine afterwards.......Tom

you will either need to drill out the flywheel bolts(as on Tom's, and GLF we did), or use the flywheel and pressure plate from a ea82 5spd(2 or 4wd)
the ea82 has larger flywheel bolts
other than that it will fit,
i got one in my 83 wagon, i moved the battery and coil to the other side of the car, as like an ea82, using the ea82 battery cables, and lengthening the wires to the coil, leaving the disty wires alone.
you will want a distributor from an 85-86 distributor to work, but you can also modify the ea81 distributor to fit the ea82 if you swap out the little gear on the end.
