Ok, I am putting a 94 vette Lt1 and 4l60e into an 89 firebird, and I can't find any information on what to use as a trans crossmember for this swap. the transmission mounting holes are in a completely different place on the vette 4l60e than they are on my 700r4, I was wondering if anyone has done a similar swap before...and what they used.

I may just end up going to a steel fabrication shop and have them fab something for me.

 

I believe the transmission is a different length so you'll need a new driveshaft too, and I think you'll have problems mounting the torque arm too.

 

I hope you are misinformed, I recently picked up a 1Le aluminum driveshaft for my car...grrrr

 

some fabrication is required:

vettes dont use a crossmember.......the tranny is mounted to the torque arm
