Slim, I used a chisel type exacto knife to remove the exhaust pipe ,muffler and tailpipe. When you remove the muffler and parts of the tailpipe it leaves a hole in the chassis. I backed up the holes
with small pieces of sheet styrene and then filled in the holes with squadron putty. After it dried I tryed to match the floor details as best I could with various exacto blades. If you look closely at where the muffler was you can see that its not quite the same as the other side. It definitely is the amt chassis. I have an R/M 56 kit but I'm saving it to do Rex White's number X, 56 Chevy. Thanks for the props on the job,but if I had a more close up picture you would see it's not that great. I just could not leave that ugly molded in exhaust even though its a curbside shelfer.
