I purchased these wheels a number of years ago and never ended up using them.
(2) 6" rims - 2.5 back spacing
(2) 8" rims - 3.75 back spacing
2.500 center hole - 3.75 bolt circle - .625 drive pins
I would take them apart and put in new hardware and reseal them before use. All of the rims are in good shape.
If anyone knows what they were originally from please let me know.
$600.00 or best
