'69 Barracuda T56 swap, floor, cross member
To address the muffler to pinion yoke clearance issue I loosened the H Pipe clamp and was able to pull it apart 1/8 inch or so. This allowed the mufflers to spread apart by rear yoke to provide good clearance. There is more clearance now between yoke and passenger's side muffler compared to when car was last together with the 7290 yoke.
Downside is passenger's side tail pipe above axle is only 1/8 inch away from frame rail. I don't think its gonna hit because TTI hangers are very rigid that system doesn't move around back there. But if it does I have a two post lift in other garage. So I'll deal with that once the car is able to move over to other garage under own power which is not too far away.
