Surpise Surprise Surprise

well today i took on the undertaking of swapping out the rear ends from the donor car to the car im building and i found a nifty little surprise. underneath of the car im using i found a rear end that i dont recognize. the casting numbers are c90w 4025a. i tried to google it with no luck. the thing that struck me as odd is that it does not have a removable center section like the 8" and 9". instead it has a differential pan in the rear with the drain plug in the front. any ideas as to which rear end it may be? and as i side not this must be the smallest one ever made because the 8" dwarfs it.

 

Sounds like the 7.5 rear from the early 69.5 & 70's. Is it a 4 or 5 lug?

Yep, sounds like a 7.5 rear - same as the one I took out of my 69.5 and couldn't throw it away fast enough

 

it is a 4 lug

 

It's a 7.5 rear

 

Yep its the little baby diff. Very weak. My 70 had that diff.

 

Can't be a 7.5 cause Ford never made one. It could a 7.25" or worst yet a 6.75" or 7"

 

7.25 in the early Mavs.

 

ha ha before swaping mine i welded the spyder gears up and burnt the tires off of it

then i pulled it and put the 8'' in then a little bit after that i put a 9'' in it

 

Ah sounds like the rare 9" that my buddy had in his boss 302 Maverick that came like that from the factory lol

 

I just knew it was little

 

so what your saying is i should make it into a table.

 

my buddie had one a dem too.mm hmm!!!!!
