Post by: old_bill on February 18, 2007, 04:19:22 AM

What type of thread would have been used on unit/pre unit Triumph twins bolts and studs? I would like to make my own and don't know what dies to buy.

It really does depend on *what* *where* and *when*

As various British Standard threads were used, the Triumph Co. mostly changing over to 'American' (UNF/UNC etc.) thread forms from around 1968-on.
