looks like a 10bolt to me. 12bolts have a squared off bottom portion.

Well, I count FOURTEEN bolts, people, and it sure looks like a 14 bolt semifloat to me.

I name it "Bob", btw.

So the 14sf is round like that? I've never really paid attention to what one looks like I guess.

 

[thebird00]

Thanks for the fast replies too!

the 14 bolt has 14 bolts. the 12 bolt has 12... It's a corporate thing

wait, you're saying that if it has 14 bolts, it's not a 12 bolt? wtf? that's just crazy. . sure it didn't just come with 2 spare bolts, like those buttons sewn on the inside of shirts? car companies always like to give you more than you paid for. they're really generous.


since it's all big and stuff, i'll say it's Jennifer Lopez's rear.

Thats a good reference guide.

 

[vortec]

i haven't seen this asked... anyone know why the pumpkin is so drastically different between the sf and ff? seems like it would be cheaper to produce just one, but maybe slightly modified so that it would accept both types of diff/axle setup.

Ah yes, I remember now. my '64 had the FF.

Not a FF 14 bolt, they didn't start until the 70's.

It would have to be an Eaton or dana rear end.

 

[Cowboy_80]

nope 14bolt FF. I put it in after I blew up two Eatons.

 

[Mtndewblazer]

14 Bolt for sure.

 

[guz71]

Yea its a SF 14 bolt, It looks like some one grinded some of the lip of the bottom, that made it look more round. I too thought it was a 12 bolt at first glance.

 

[thebird00]

I thought it was a 12 bolt, but kept counting 14 bolts. Glad ya'll cleared it up for me. I'm a little wiser now, just like everyday I visit CK5.

 

[JohnDeere]

sure its not a 12bolt with one of those aftermarket 14bolt covers
