Will a cj speedo cable work on an M38?

[Ryan]

I have a speedometer cable for a cj that I was considering using in my jeep untill I get the correct one. Will it work? It looks like the ends that go into the transfer case are different?

Post photos of the two ends.

I will try to take pictures tonight.

Are the rear bearing housings that the cable hooks into the same on CJ/M38/M38A1?

No, I had to change from a civy to the early M38 speedo cable WO 801093 (54 1/4 ") and had to change the sleeve and gear. Looking at the ORD 9 Pg.336 the early and late speedo cables used different part numbers for the speedo gears.
Anybody have both the early and late they can compare???

Here are some photos of the late (after MC44029)(Jan 52) speedo gear.

My wife didnt have her camera last night. I am definatly going to have to post pics of what I have b/c im not sure exactly what I have. As soon as I can I will get some pics.

The CJ2A & CJ3A WO part numbers are:

Sleeve- 636396
Gear, drive 4T - A-1511
Gear, driven 15T - A5707

Note: CJ2A and WWII MB are the same except for the driven gear MB uses A-1512 which I believe is because of the different gearing (T84 tranny) and final drive (6.00-16 tires with 4.88:1 axles).

The early M38 numbers are:

Sleeve- WO# 801092, SP# 55-452-2, ORD# G740-7697552
Gear, Drive 4T - WO# A-1511, SP# 18-452-2, ORD# G740-7673166
Gear, Driven 15T - WO# 801696, SP# 18-452-9, ORD# G740-7697553

Late M38 and all M38A1 numbers are:

Sleeve - WO# 806719, SP# 55-454-3, SW# 418991, ORD# 8328481, ORD STK# G758-8328481
Gear, drive 4T - WO# A1511, SP# 18-452-2, WG# J2-169 or J2-169A
Gear, driven 15T WO# 806718, SP# 448361, ORD# 8328480, ORD STK# G758-8328480
