420A Measurements Needed

[BLACK'98DSM]

I have an inquiry for the few and far members with 420A. I need some dimensions for the belt tensioner hardware. I'm referring to the long reverse thread bolt and the tensioner pulley mounting bolt (87061A). I know their thread pitch but need to know the thread length and total length of each.

This assembly has been removed from both of my personal cars and I'm currently sold out on the seven I had in stock. I've noticed a high demand for these recently. So I'm trying to expand from distributing used parts, to actually having new hardware for us to use. By "us" I mean everyone else of course. I don't have a desire to use the OE tensioner even if I revised it

87061a is i believe 90mm, i remember when i first got my dsm i snapped it no knowing it was reverse thread. just used a pry bar to get tension and tightened the pulley , going strong for 3 years now!
