OEM 9 inch FF questions

[nismogizmo]

There are a couple 9 inch Full floaters in Phoenix I have found, My concerns with them are mainly longevity, and changing bolt pattern on hubs. Are there hubs out that fit the OEM 9 inch FF that will change the bolt pattern to 6x5.5"?

By OEM I assume you mean a FORD 9" FF that came in a production vehicle - can't think of any common applications. What are these supposedly taken out of? Are you sure the are FF?

The couple I have found are in 3/4 ton vans, mainly mid 80s ambulances.

But I am not positive thses are full floaters, I haven't personally seen them, I just found them using the junk yard search car-part.com .

If they are FF they are probably Dana 60's, not 9 in., if they are 9 in. it would be a SF, 1/2 ton with 5 on 5.5" bolt pattern.

Op maybe they could be gm "14 bolt" FF which has a removable pinion and 14 bolts holding on the rear cover (hence the nic name). From the front they look like a 9".
