Bought out a Walker distributor 23 years ago and still holding lol! This is an NOS Walker cold rolled steel tailpipe for 1954-8 Dodge trucks as follows:1954-8 Dodge 1/2-1 Ton 6&8 Cylinder(Exc. 108" wheelbase and 1957-8 Dodge 300-P400 3/4-1 1/2 ton 6 Cyl. This is Walker#2276-7 and replaces Mopar#1501960&1788434. 45@. It's the one on the far left. I also have NOS headpipes for these trucks with 6 Cylinder only for an extra 45. If you want both pipes will sell for 75 bucks. I have no mufflers remaining. Call for apt to inspect or purchase. Thanx
