acme, it sounds like you and i think alike.....
i too like the g-body front end and, here's a tip, circle track racers like 'em to so there's plenty of "trick" stuff out there....
another idea i've had is a late model tacoma 2wd FE assy.
about the same width as a g-body but real similar to a MII in design....
trouble is that here in colorado everybody thinks they need a 4X4.....
