Does anyone know if MT sells installation kits for their ring&pinion sets for the 47-55AD's. Have a ring & pinion along with the installation kit on order with Patrick's. Been waiting 6 mos and still don't know when I am getting them. Very frustrating. But I do not want to cancel until I have another source.

MT has the R&P in stock.
I think he does not sell any installation kit.

Classic Parts sells an installation kit. You'll have to call them to see if your kit is in stock.

Make sure it matches your year. There were differences in a few parts between 1947-1954.

I do not know about 1955st series 3.55 R&P conversion.

Looks to me like MT has these gear sets "Stacked To The Ceiling" & ready to ship.

If you observe, MT advertises them for 47 to 53. With a little modification, they can be made to fit a 54. However, the 55 1st and later is an open drive shaft and requires a completely different gear set. I agree with Tim. If there is a 3.55 gear set made for an open drive shaft, I have never heard about it.

"With a little modification, they can be made to fit a 54."
What is needed in 1954 is an earlier 4.11 1/2 ton truck carrier for the ring gear. Just swap it in.

"However, the 55 1st and later is an open drive shaft and requires a completely different gear set. I agree with Tim. If there is a 3.55 gear set made for an open drive shaft, I have never heard about it."
There is a 3.38 R&P set available for the later, open-driveshaft 3.90 rear ends.

Here are some sources (MT does not sell a set - unfortunately):

Patrick's 3.38 R&P gears - could be slow to deliver

It sure looks like MT carries those 55-62 gears to me.

Thank you very much, simplex

Joe would be irked by my incorrect information.

Looks like that post on the HAMB was made 28 minutes ago by MT? (a few minutes before your submitted your post here)

Would someone post contact info for MT?
You have to be a HAMB member to contact him at the HAMB link, I think?

check your P.M.

Does anyone know the difference between the two installation kits. I have a 50AD but the rear brakes are not the Huck type. I am assuming that I have a 51 or newer rear end. I have suspicions that the truck maybe a 52. So I am trying to figure out what kit to buy. The front end has the Huck style brakes.

One difference might be the Okie (drive shaft) Bushing?

1940/41-1950 bushing

1951-1954 bushing

The bushings is the only different in the photos (if photos are correct):
41-50 parts set
51-55 parts set

Your axle should have a code stamp on the housing. It will start with H for '50, J for '51, K for '52, etc. I think for the half tons.
Check

My 51 had a 50 axle, with Hucks, that's how I figured it out.
