Default old rockwells

a friend has 4 old frontloader rockwells that i'm thinkin about buying. anyone have any info on these? the axle tubes are round where all my searches for a frontloader rockwell the axle tubes are square. i'l looking for gear ratio and strength mainly. he said the front's a pass. side drop also.
i don't plan on running a huge tire. lookin to stay between 35's -40's but i mainly want these for the gearing they might offer as i'm looking to run a 4 banger in my rig.
thanks. john

How heavy are they, and how big is the diff on them?

Gearing aside, they seem like huge overkill for a 4 cyl and 35s.

they don't sound like Rockwell's
they sound like sterling or gm 2.5 to 5 ton
Rockwell's ore top loaders, the gm and sterlings are front loaded
the Rockwell ring and pinion lay flat (lots of ground clearance
gm and st. run vertical (not much clearance at all)
Rockwell's have square tubes
gm and st. are round
they all came with super low gears starting at 6.38 i think
but they weigh about a 1000# a peace
and are in no way worth it for 35 to 40s with a 4 banger
even with the gears you'll be burning clutches and not spinning tires due to the weight or the axles and rim/tire size you need to make them work

There are front loading rockwells, too, but the ones I've seen all had square tubes. Same housing, actually, just rotated 90 degrees. There's a build on Pirate with some..

uh you could go to a dana 44 with 5.38 gears as with a 4 banger and 35's you aren't going to be snapping anything especially if you built them right. these seem like way overkill.

40s would be snapping axles with D44s and low gearing (crawl box) and/or aggresive driving, even with a 4 banger.
