I picked up a 14 bolt ff with NON-slide on drums, pumpkin housing is ribbed top and bottom. (was told it was out of a 80s truck, unknown if swr or dually)
I've taken some measurements, below is what ive gathered:
WMS-WMS = 67"
Backing plate flange to flange = 54"
Shock mounts are 31" oc from each other
Leaf spring perches are 47" oc from each other.
The hub is a swr hub, not the dually.
I plan on using this to replace the 12 bolt truck axle, and understand that the perches would have to be re-welded. I just want to see if there is any other information I am over looking because this is my first axle swap.
