IIRC: 3.54 and down and 3.73 up is the carrier break.

You should be able to use the spiders though. AFAIK they are the same.

The spiders should be the same as long as both are Dana 30's with open diffs.

just a thought... if at all possible, look for a P-n-P '95 banger 4.10 axle as a replacement. It will have the larger u-joints. The posilok can be swaped over. It will cost you more in parts to re-build the 307 axle than your current one.

If you know how to set-up R&P gears, you are ahead of the game.

But, if you knew how to do that, you wouldn't be asking any of these questions.

You are looking at a few hundred $ to do that.

And the search function here can be your friends.

The very first link in that search was done by my friend Stu. I highly recommend you study/read thru his site. LOTS of info.

Google
