Question Exhaust Pipe Question

OK. 78 FORD F-100 WITH 302. JUST THE OTHER NIGHT I WAS DRIVING HOME AND HEARD SOMTHING BANGING AROUND INSIDE THE ENGINE. GOT HOME QUICK TO FIND THE EXHAUST PIPE WHERE IT TIES INTO THE EXHAUST HEADERS WAS JUST HANGING THERE. NO BOLTS OR ANYTHING. SO I WENT OUT AND PICKED UP A NEW HEADER GASKET AND EXHAUST FLANGE. NOW I GOT TWO SMALL QUESTIONS.
A. WHAT SIZE ARE THE BOLTS AND HOW LONG DO THEY NEED TO BE.
B. I UNDERSTAND HOW THE GASKET GO'S ON BUT WHERE DO I INSTALL THE FLANGE AT. BETWEEN THEM?
AS YOU CAN TELL I NEVER REALLY WORKED MUCH WITH EXHAUST SYSTEMS.

3/8 x 1 1/4 inch will work perfect, pitch doesnt matter, but 16 ( coarse) is most common

I am not sure what you are asking on your second question..... the gasket goes in between the two flanges..........

If I can be of more help, chime away....

I gotta agree there, I just cut the flanges off all together, and bump the pipe up to fit, a couple of circle welds later.... no more problems!!
