Hi, more questions on EJ into EA swapping, about the adapter plate thickness:
All I can locate in my area is 1/2" aluminum. The best known conversion was done by Subarino with an adapter plate made from 12mm aluminum. I can have a machine shop bring the 1/2" down to exactly 12mm, but is it worth it? We are talking .7mm difference here I believe, and I just read a post that says the mudrat plate is made up of two 1/4" peices.
The perfectionist in me says get it sanded to 12mm, but maybe it's totally unecessary. Opinions?

it's a non-issue. it means that your throwout bearing is that much further from the pressure plate, and it can easily be negated by the clutch cable. you'll never see it. save your money for getting the flywheel balanced after having its bolt pattern altered to fit the EJ.

I just picked up my aluminum for the plate today. They had a scrap lying around just the right size that they were calling 1/2" I took it home and measured it - exactly 12mm thick! So that's cool. I also bought out Lowe's supply of thick metal cutting jigsaw blades. $40 worth. (I'll return the packs I don't use. Just didn't want to run out) Now to finally pull the EJ motor...
