Hello. 50W, I thought you might like that.
The "68 - 72", (actually 68' and older) GM full floaters are fun to work on. Yes, been there, done that as well. There is still one or two running under a figure 8 car even to this day. To bad we can not find 3:73 ratio. It took a long time to find 4:10. It seems they most all were 4:56. The third member on these drop out the front like an 8 3/4", but also have a bolt on rear cover. A builder can also weld on upper control on brackets as easily as welding on brackets to an 8 3/4". These pinion yokes are not fine spline. If you want a round yoke for these, simply make a hybrid. Join the two halves you want, and if done correctly, can work well. As time passes by, they are getting harder to find parts for. David Bryan

Depending on what year truck it is it might say in the glove box.

Most but not all ho52-ho72 rears had the 4.56 ratio. If you do a simple google search you will find that a lot of people have 5.13 and some had 4.10. The one I have in my shop is completley origional with gm gears and is 5.13 ratio. I will gladly post pictures.

I would guess dana 60.
I want to argue with you Dave i bought a rear end from raptor fab and he says its a dana 60 full floater out of a truck with 4.11. But the problem i have is it has these things on the end of the axle with five lug axles. There is no way it is a dana 60 full floater! So that must makes you a liar. Haha.

I just found this thread.
Couple of things.
The suicide lincolns (66-69 Continentals) with the 9" rearends.
Were they all actually the 9 3/8" or were some the 9"?
Are any of the internal parts of the drop out 3rd members interchangeable other than the pinion yoke?
5 Lug Dana 60's semi floater
I have a 73 Jeep truck with one.
Any value?
On page one you were talking about the 68-70 Olds and Buicks with BIA. I have a 70 Pontiac with BIA, would it be the same as the Buicks and Olds from that years range. It also looks a bit different than the 71-76 BIA that most use.
Also on page one you didn't mention the GM 10 bolt. Should be included for basic info for some newer people.
Thanks for a great topic and great info.

Hello. Most should be the 9 3/8" (war case)(some say 9 1/4", not correct), but with cars that old, it would be best to check. Over 40 years, things could have been traded, or changed out. A 9" third member will bolt right in to those housings. The only internal parts that change out is the small roller bearing at the rear of the pinion shaft, but why? You could also try and reuse the 3.062" carrier bearings, (in a 9" after-market case), but why? I guess in a used case, in a pinch? Perhaps. Now, if you find one with a "trak loc" and has a 3:50 ratio, 31 spline, then that unit could be re-sold to a steet guy.
The only problem with the Jeep Dana 60 (or some 60's Ford pickups), 5 lug, is that the axle tubes are small in diameter, and week. They are also the small diameter alxe shafts, mostly coarse spline. You could use the assembly as is, but then one would want to have spare axle shafts, and that could be the problem. Great gears, bad shafts.
The 68' - 70' Buick axle shafts are 30 spline. The same years Oldsmobile are 31 spline. Both are 5 on 5" bolt pattern. Both are bolt in. Wheel bearings vary. Jon, (CRUSHER) could probably tell you about the Pontiacs.
And, about the GM ten bolts, on page one, more to come.....David Bryan

hey david what are the chances i break the axles in my 14-bolt semi floater? it's stock out of a chevy 2500 and what are the chances it's a limited slip? maybe a better way to ask this is: what is this rear end comparable to in strength? Are the axles likely to break in a derby similar to Mayhem (a derby with many tire shots?) |

TO MAKE A LESS EXPENSIVE HYBRID 9 INCH REAR, YOU GET A FORD 9 INCH FROM A PICKUP, FROM SAY, 74 TO 1980 -ISH, AND BUY A 68 TO 70 OLDS 98 OR DELTA 88 OR DELMONT 88 12 BOLT REAR END. BAISC SHORT VERSION IS, CUT OFF THE 9 INCH BEARING ENDS, THROW AWAY, CUT OFF THE OLDS BEARING ENDS ON THE HOUSING, THROW HOUSING AWAY, WELD OLDS ENDS ONTO 9 INCH TUBES, BUT------- HOUSING SHOULD BE NARROWED IN TOTAL,#/4 OF AN INCH.. THIS IS DUE TO THE 68 TO 70 OLDS 12 BOLT, 31 SPLINE AXLES BEING 3/8 SHORTER THAN STANDARD 71 TO 75/6 12 BOLT AXLES. THESE OLDS AXLES FROM 68 TO 70 ARE FAR EASIER, TO FIND, MORE PLENTIFUL AND CHEAPER TO BUY THAN THE 71-75/6 12 BOLT AXLES... DONT FORGET A FULL SPOOL FOR YOUR 9.... USE THE OLDS REAR BRAKES OBVIOUSLY, OR HAVE DAVID BUILD YOU A DANA 60.......LOL
