Assuming you are referring the the M/T sc-5 wheels in the later pictures. I like them alot and for the current blow out pricing on ebay they are tough to beat.
They are 17x10 on back with a 6.21" backspacing.
No mini-tub
I am running an offset spring hanger and a 5mm wheel spacer.
Rear end is an a-body width 8-3/4
