I bought a DSS flange for a 04 GTO and it did not come with bolts.

Anyone tell me what size I need to get?

I think its a m12x1.500 but i have no idea on lengths or size of the shoulder I should get.

Ive tried all the local stores around here. I am going to have to order them.

Did you try DSS? They should have them, they sent the bolts with the 2 pc I bought from them. At a minimum, they can spec. what you need.

Mine are definitely fine thread 1.75
I was going down a random thread rabbit hole...

Just for the next guy who is searching and finds this thread.

The torx e18 bolts through the guibo to the threaded pinion flange are M12x1.5

The 18mm head bolts w/ 19mm nuts through the shaft flange and guibo is M12x1.75

If you were to buy a used one piece driveshaft with a direct fit flange and it comes without hardware. The bolts you are looking for are M12x1.5 x 40MM
