Boy Alvin, that would really be great if you could get them to take a look at this project.
That's one gear maker that I didn't contact when I was looking into this project some time
ago.
Yes the "gear set" the we, at least me, have been talking about refers to the Ring and
Pinion. The late model (67-72) housings are plentiful but are stuffed with the 4.57 gear
set so finding a housing to install a 4.10 or 3.90 R&P in isn‘t a problem. I just scrapped
out three axles housings last year, all were complete with the 4.57 pumpkins. Keep in
mind now, we're talking about the Eaton HO52/72 axles used in the 3/4 and 1-ton trucks.
Any decent sized machine shop now days has a CMM and could copy the geometry off of
a stock GM 4.10 set of gears. A lot of the shops have software that will take the CMM
data and convert it to machine language that the CNC equipment can use. In other words
the programming is relatively easy in a modern shop.
