735i retro

Does anybody know if there is a four wheel drive tranny and transfer case that will bolt up to a 85 735i? it's for a project I might try.

The best best is to find an older model that had a four wheel drive system. I can't think of any vehicle in the same era that had four wheel drive.

But if this is a project car, I'd say find a smashed 3-series with x-drive you can pick up for pennies before it get's crushed and salvage the drivetrain from that. The problem with project cars is there really isn't such a thing as "bolt on" retrofits.
