Thats interesting Jeff. I was hoping my original E-mail would bring out info
like this that you experienced guys have. It sounds like the Pit Stop folks are
covering everything with the larger unit. Is there a marking on the carrier
that would tell me if I have a 50 or a 72? I did a punkin swap
A second question for you, Jeff. I have gotten the impression that the ring
gear in an HO72 is 12.25 inches in diameter. Do you know if thats true? By the
way, I just did a Google search on HO50 and came up with zilch. HO72 has a
number of hits. I wonder if the HO72 designation is kind of a catc
I don't think that the center section has any markings that designate whether
it was a 50 or 72. The 5000 lb and 7200 lb ratings refer mainly to the load
carrying capacity of the rear axle as an entire unit because the outer wheel
bearings and brakes etc are different. I'm thinking that origina
1958 GMC Master Parts Book lists H050 as the rear axle used in 55.2 thru 58 15x
series (3/4 ton) trucks and H072 for same years 25x (1 ton) trucks. I'd guess
that would make H050 and H072 "official GM designations".

Well..I just went out and looked and based on your description, Jeff, I have
an HO72 with the load bolt. The gear ratio is absolutely 4:10. I have checked
that, So, no matter what else, we know we can get an HO72 with 4:10 gears. Now
I am back to square one and that is can I find 3:73 ring and
DO IT ! .
You'll ove the improved throttle response at all speeds & loads ,
better fuel milange and the engine will last much longer too .
They need the flywheel as it affects crankshaft balance , for only
$150.00 you're getting a bargain .

Jeff ;
Are you talking about the small diameter internal oil tube that goes
through the engine and feeds oil to the rockers on early engine ? .
A link to a picture would be helpful here .

Are just the ring and pinion interchangable between the newer and older rears?
If so O'reillys has all the newer ring and pinion ratio's for just under

Hi Roy ;
Is there some manner of external ratio identification ? like a tag
to look for or number stamped into a rib etc. ? .
I'm physically unable to go popping these out of the old vans but I
do find lots and lots of the vans in Pick-A-Part , it'd be good to
know how to discern which rear

I sure wish there were a marking of some sort externally, Nate. I have called a
few junkyards and while they are willing to pull a carrier from the type of
vehicle I ask them to, they won't check or gaurantee the gear ratios.

cyl and V8 for a 58-59 truck? is it different on the 55-57? i've owned a 56 gmc
and 5 58-59 3100 in my life. i know the 56 was different from the later yrs due

Read your manual thru, look at pictures again. The bellhousing is the "hunk of
metal" you refer to. It can't be removed without pulling clutch and flywheel
out first, as there are six bolts behind the flywheel. You shouldn't have to
remove it at all. It also has the motor mounts, so if still in
