Been doing a lot of research for my T-56 Magnum install. Seems like you don't really know what's going to work until you actually get the parts and try installing them. Dale from Texas on his build thread just ran into this. Another perfect and kinda funny example is here. Watch the time frame of 0:39 to 0:54 on the following video:

Typical marketing stuff right? Now fast-forward in that video and watch the time frame of 2:44 to 3:45. And then later in the Part II video clip, they had to build a custom crossmember also.
That right there is a perfect example of our pro-touring build challenges. The marketing and claims don't always hold up in the garage.
For my build, I'm confident I have all the correct components with the exception of the hydraulic throwout bearing. I think I'll buy 3 different ones(GM LS, GM ZR-1, and RAM) and use the one that fits and return the other 2.
