we'll have to hook up Mike!!... you're more than welcome to check out my Toyota box and make any measurements you need before you run out and buy one... i kept running into conflicting info so it took me awhile to decide on this combo... ALSO>>> my BIG PLAN was to have ALL CHEVY or at the very least ALL GM stuff on my truck... "aftermarket" would have been okay but nothing from any other auto builder other than GM and NO FWRD stuff even if is was FREE... and i have a bunch of '34 FWRD truck stuff on hand too!!... it is still KILLING ME to have to use this Toyota part on my truck instead of a GM part.. there is a Dodge box (made by saginaw) that is also supposed to work but they seem to be harder to find that the toyota and the pitman shaft housing seems to be a bit shorter and i need some extra length inside my frame... oh well... it ain't over yet...
