Title: thread size of 376424-S7 muffler hanger nut
Post by: gjz30075 on July 01, 2017, 11:28:18 AM
The nut referenced in the title is for the 66 (and others) dual exhaust muffler hanger that is under the rear seat.   

The hanger studs on my 66 GT350 looks very oem but the only nut that fits is a metric M10 x 1.5.   Any 3/8 nut I try, both coarse and fine, jam up within
one turn.    Might be the paint on the studs but I'm afraid to go further.

Not as thoroughly as I should have.   Went back and found it.

Thanks!
