BBduster

One of three choices if you don't want to cut the fenders:
Original stock steel manifolds
custom make your own
or go to http://www.engine-swaps.com/frames/frame_73upABFMJmount.html and call thier number and ask them about their "stock manifold style" headers for BB Abodies.

Their may well be other companies with headers that may work but most I know of are a pain or cause interference with something.
