Uh ohh, did we start censoring bitch around here? When the **** did that happen??? :shrug:

Yeah, if you can find a 14 bolt, and it's 6 lugs from a 88-98, then it should fit and be the 14b Semi Float cuz 14b Full Float is 8 lug only.

Same common ratios are available. 3.42 and 3.73 probably being the most common in 6 lug and some 4.10's will be out there too.

Jack it up and count the drivesahft turns to 1 wheel turn. I have a thread in Differential to tell how to do it.

OR, do you have a SPID label in the glove box with all those letter codes??? Usually the Gear Ratio Codes start with G. Let me know all your codes that start with G. If the axle has never been swapped out then the RPO codes in the glovebox will tell us.

OHh, you've take the cover off? Well then look on the ring gear for some #'s That will tell you what they are. The first long ground of #'s is the part #, then there should be 4 more # single and/or double digit #'s Like a 41 9 1 92 Get those 4 #'s and I can tell you what it is.

How does the ring and pinion look? You sure you just don't need new spider gears???

Ahhh OK, it's past just needing spiders only. It could be the pinion went first and the broke pieces got tangled in the spiders and broke them. I have gotten lucky before and shredded the spiders and I do mean shredded them. Had a bit of horsepower and did a hard launch and just started shearing them off. Opened it up to a handful of spider teeth. Replaced them and it was fine for a long time. Til I broke the ring gear.

Yeah, you're cheap out option is to find another working axle.

You sure it's the right gear ratio? If it's not, then you'll need to change your front axle too.

Ring gear on both axles are 41 teeth and pinion gear on both are 11 teeth so now I wonder what the ratios are in it

Thats easy to figure out just divide 41 by 11 thatll tell you the ratio
41/11=3.727272727272 or in other words 3.73
