^ You're looking at aftermarket, frame mounted ones? That could be the reason for the difference. I was curious if the factory trans mounted bars were different.
Same rearend housing configuration, same trans basically, wonder why would they would be different if they are?

 

I've had some difficulty in locating any good info on OEM torque arms after a few quick web searches, eveything seems to come back to aftermarket setups. I guess I will run the Camaro with the stock arm and see how it goes, my real concern is more preventative than performance I think, not really sure that the 3.8 is giong to demand all that much of the torque arm. I just dont want to have any issues in a bad place.........

here is a pic of the Spohn arm I guess I would use if there is an issue with the factoru one. What do you guys think?

 

69 that is from the oem book, pretty sure all the aftermarkets are the same. i think the stock one will work. the spoon t bar will be over kill but you wont have to worry about it.

 

Im with ya Craby, gonna give it a try, thanks for all the input guys, appreciate it! If something goes "bang" Ill be back to let ya know what happened, thanks again...........

 

Stick with a full length TA, my preference would be the UMI version... Might want to phone Sam Strano and ask your questions: Strano Performance Parts - Parts Catalog
