Ok heres the deal, my swap is an 04 gto drivetrain into my 87 trans am... i got it running and driving, main thing is i need pictures from you people who have used the trans am /camaro motors in your cars. the 4L60e tailshaft housing on the gto doesn't have the torque arm. which doesn't bother me at all, better off that im missing the extra flanges since i'm using a jegster torque arm anyway. i need the pictures so i can compare tranny mount locations.the gto has the mount centered exactly on the tranny. are the fbody mounts offset at all due to the torque arm??? pictures will tell a thousand words.. right now my mount doesn't line up w/ the spohn crossmember holes, there off by like 1 cm. i may need to get a tailshaft, but i would like to see pictures, before i spend the cash.... thank in advance for your help people....

 

No off set to the stocker but I do believe the LS1 mount is slightly further back than a sbc based trans. I have pics here of my c mem but dont know if its of any help. I sure as heck wouldn't go through the hassle of changing the tail shaft for something as simple as modifying a cross member. A little drill here and a little weld there does the trick for me everytime

I'm sure searching will find you what you need but heres the link of pics of mine
