So when my inner longs were repaired, the attachment point for the seat belt on the drivers side was not put in. now I have this old lathe I've been playing around with and decided to make an insert to weld it there for the bolt. I find a bolt that fits and check the treads and it comes up 1.25, checking it with my tap & die set, its not 10 x 1.25 and the only 11 I have is 11x 1.50.
is this thing really a 11 x 1.25? .. What an odd size |
