1957 exhaust header pipe nuts

[Dan P.]

I talked to a guy who says he has the original drawing for the header pipe nuts. That they are regular steel nuts . Not the crimp nuts everyone sells. Any idea's on this . Thanks in advance.

Dan, If he has the original blueprint then he should have the part number. If he can provide your question can be answered.

As it turns out he can not find the drawing . The part number in the assembly manual starts out 367 but i can not read the rest in my book.Does anybody have AM that has the the whole part number.In the standard parts catalogue a standard 3/8 nut is part number 120377.Any body know the part number for the crimp nut that was available for years .

The '57 Pts Bk still has a Gr.8.900 Std Parts section in it. No 7 digit nut part #s are listed in it. Some listings under a Google search for that # will take you to a listing for the crimp nut, but the reasoning/connection is not clear. Maybe the answer is to contact the seller of that nut and ask he/she "why" they believe it.

Not sure what you mean by look this number up. A web search of "3671946 nut" brings up numerous vendors, GMwiki, etc.
