Okay I'd like to help but can't read the whole 4 pages. From what I've read, you have a 318 V8 and want to slap on a Thrush to get some burly exhaust right? I just fabbed up a dual exhaust setup for my '72 F100 including headers (Summit brand) and straight pipes with turndowns. Welded it all together, of course, no clamps. So if you need some help, feel free to ask.
