Opening Pandoras box
 

Well, after alot of magazine reading, I've come to the conclusion that I have FMS rear axles, not strange or mosier. They are 4 lug, not 5 lug and dont have any extra holes for extra lugs(conversion). This comes on the heels of trying to get more rubber to the ground ie: 15 x 8 Weld pro star 96 series and some MT's or BF drag radials.

My question is, I know my vehichle has 410 posi, How can I identify the maker of the differential? what if its 28 spline? what if its 31 spline. So far I'm getting 431 rwhp and plan on adding 125-150 hp power adder. Oh, and 456 gears.

Any thoughts on where to buy either starnge or mosier axles? at a good price? If I need the differential, then any ideas where to get a package? Auburn pro, axles and c clip eleminators, LOL I dont even know if it has c-clips or they've been replaced with the eliminators...................They draw backs to buying a car from someone who knew nothing about what he spent his money on:o

Well, I am NO WHERE near where you are in HP (but give me some time :D)

I have rebuilt my rear end (after I blew it up :D).

You can easily tell if they are 28 or 31 spline by simply counting the number of teeth on the axle. Sometimes it's hard to find the maker of the carrier just by looking at it, if it doesn't have a brand on it.

I have FMS 3.73's and an Auburn Posi diff. I love it and it gave me lots more torque to the road then I have in the past. I can spin my tires longer and in higher speeds/gears. I know that is not a good thing but my street tires suck....

I bought my carrier from Tommy Vaughn Ford (a Ford Racing local dealer). Mine was only $388. I dont know if it would hold the kind of HP you are looking for but then again, Auburn is awesome!

Hope this helps...

You can get a package that includes new 31 spline axels, long studs, and c-clip elims for like $380.00 directly from strange. This is the package I run and its great for high power cars. There number is 847-663-1701. Powered By Ford (407-843-3673) has the best price on the Auburn Pro 329.95. While your doing all this you will also want to pick up a rearend girdle Ebay has a Mac that go's off in 8 hours current is $99.95. http://cgi.ebay.com/ebaymotors/ws/eB...tem=1811451597
