TTI Exhaust on a Duster anyone install one?

I went thru the same thing on mine. Alot of swearing and carry'n on. I also took the seat belts out and put the longer bolts in and was way off on my 72 Duster. I believe i ended up using the original tabs on the floor boards between the shocks that held the factory tail pipe hangers. I had to drill them out bigger to accept the larger bolts. I worked on that for days. I am still not satisfied, the brackets are not even, one is twisted up. I feel I am going to go with the factory hanger and a 2.5 clamp to hold them in place. The hangers they send are so big... and there is no need for them that big, hang'in down looking like s--t. I also had a nightmare on the downpipe on the driver side. I have factory manifolds and that pipe was into my kickdown linkage and starter and something else. So they sent me a pipe for a manual transmission and it was alot better, did not have to cut anything either.
