[SCOTI]

How low is it? Mine is dropped about 8" in back (flip-kit on 8-leaf spring pack + Bell Tech shackles). I ran 10" wheels w/5.00"BS & was about .750" from the inner tub wall & .500" from the outer lip.

I can't see 11's fitting on a low truck w/o mini-tubbing. They might fit, but definitely would be TIGHT. Even then, your initial question reads "whos got the most dish?". Rear end width plays a big part on the back-spacing required for that deep dish look. My 74's 12-bolt is stock length so that previously mentioned 5.00" BS is about neutral; 4.00" BS would have more dish but interfere sooner w/the outer fender-lip. 4.00" BS on an 11" wheel would look deeeeeeep but the rear housing is going to need to be narrowed.

Board-member 'Crawdadfox' has a narrowed rear end on his '77 & runs 10" wheels w/4.00" BS (22x10's). His wheels look killer w/the deeper dish vs. mine but the added expense has to be considered (unless you've got connections for that sort of stuff). Look up the thread on his "ebay 77 w/Porterbuilt F/R Dropmembers" to get an idea on the deep dish.
