anyboby smallblocked a 70's colt?

dont have exhaust pics,but i can tell you it took the muffler shop about 7 hrs. to make the turn down and forward from the headers. the bender couldnt bend it tight enough.i used summit block huggers,then it turns forward,then down then back in front of/then under the crossmember.it runs straight back approx. the length of trans,then turns up and follows the floor back to a pair of one chamber flowmasters,then over the axle through two tips under the rear bumper.2 1/2 in pipe.
