[slammed57]

Hey bud thanks for asking, the first one that is labeled (different) is used to stiffen up the frame to help strengthen the frame ( to help keep from a twisting movement).. I cant take credit for it , I borrowed the Idea from Art Morrison frames . the other (what are these for ) label , I have a T56 transmission which its tranny mount is way towards the rear , so if i ever have to pull the motor out with out the transmission I would need to to use something to support the tranny , most people use another jack or wooden blocks to support it to keep the tranny from hanging down and putting all that stress on the rear tranny mount. I just added those little mounts and build a brace that I can put in and take out to make it easier to help for support.... some people will say just pull the motor and tranny out as one unit which works , but its also a large mass to move around and trying not to band up against the truck causing dents and scratches.
