Tremec 5 speed

I installed a tremec 5 speed and new x factor cross member from American power train. I am lost as to how the cross member should be secured to the frame. Has anyone done this before and might have pics of how they did it? Do I secure the brackets to the original holes or can I use the series of holes up closer to the engine. I don't want to drill anything necessarily and weaken the brackets but I cant get any of the holes to lineup.

Loosen up the bolts on the frame and adjust the brackets so the holes line up, drop bolts in place, then tighten everything up.

I am not sure what year your car is but I have a 66 and everything lined up perfectly. I used the same holes the factory crossmember was using. It looks to me that you have them on backwards, the holes that bolt to the frame are closer to the front of the car (meaning the bracket extends more toward the rear of the car). I can take some better pics if you need them.

It's a 1964 SS car but of course its been stripped of everything that made it an SS long ago. I used the holes that the original cross member was secured to...at least where the cross member was bolted to when I started working on it anyways. Now that I think of if when I checked the numbers on the transmission that was in it it was was a Borg out of a late 50s corvette I think. So maybe someone drilled holes for the cross member and I assumed they were original holes. Regardless, the frame does have the same holes you bolted yours to as well. Which was kind of what I was asking, whether it was ok to use those holes. You did and it looks great so I feel more comfortable now getting everything bolted up. When it cools down and I get out to the shop I'll let ya know how it goes.

Sounds good, if you have any other questions or want more pics let me know. Just make sure you flip the brackets around so the trans mount will line up. I just installed mine about a month ago and it did go pretty smooth. For the record I had a TH350 in it.
