I want to get a stainless stock exhaust fabricated. I thought it was 1.5" but the front muffler clamp (20643-B5000) diameter appears to be 45mm (1.75") from one Russian parts site.

What is on my truck suggests it is 1.5 inches.

If the exhaust pipe is 1.75, then what size is the tailpipe? (could be either 1.5 or 1.75)

I have had zero luck - no one seems to know this.

Thanks
Tom

PS. Exhaust is made from Tube (not Pipe). Tube Diameter is the OD

Thanks so much for the info and pics!

Reason for all this my 74 620 had no belts and I figured I'd put retractors in it only to find that they will not accommodate a fat guy!

Frankly, I don't know what I'm going to do...

This is supposed to be a belt taken of a 1975 630.

I believe this part number was superseded however there is NO info found on the internet nor from my local Nissan Dealership including his classic parts reference.

The Takata Kojyo # is TK-720-1713C

NOTE: The character "B" shape is somewhat odd - could it not be a "B"?
