from what i understand and i could be wrong, but wouldnt the ke70 one be stronger than the ke35 one ?, due to the fact most late ke70s came out with a 4K, where as i think the ke35 came out with a 3K ?
correct me if im wrong, just seems kinda pointless..might be worth finding an ae85 rear end, and bolting that in or an ae86 if your lucky.
