Torq Thrust ST's 6x5.5 (139.7)???

[1970C10CST]

I have a 1970 C/10 and I really want to put Torq Thrust ST's on. Has anyone seen this done? I know I might have to run spacers and/or get longer studs...and I'll def have to get the hub machined. Has anyone done this? If so how do I get longer studs? There are also two choices +30 or +16 offset...what is my best choice? They are 20x8.5 and have a backspace of 5.5...does anyone know how bad the fitment will be??? I really like the stock power drum's so this is prob my best options...any thoughts??? Thanks in advance.

First off... to the boards from NC!!!

I'm not sure on the TT ST's wheels, but have seen someone use these wheels from summit...http://www.summitracing.com/search/P...=legend+wheels

Member 'djmachinist' has them on his truck in his build thread here...http://67-72chevytrucks.com/vboard/s...d.php?t=388447
