A 013 was used in the mid 80's. You either have an 012 if it's a 5 speed or an 01X if it's a 6 speed. Bolts patterns are very close.Thanks for the info FLATCHAT
do you know where i can find the nothstar bellhousing bolt pattern dimensions and the 04' Audi A4 transaxle (013E code but not sure) bell housing bolt pattern dimensions. I need it because i want to render in solidowrks before fabricating.
