B Model Door Latch needed

[Max And Chloe Hilliard]

Looking to replace my passenger door latch on my 61 B Model. The door latch has a lock set with it. I have the lock set fixed now. Tried Watts, but they don’t have any. 
 

Shipping will be to 59484 Montana. What do you have and how much do you want?

The Mack B model door lock and the International R model door locks, later 1963 type and thereafter with the push button external door handles, are identical. I had a 1965 R-200 and B model - 615 whilst both next to each other, I noticed that the 2 locks were the same. I did a bit research and it confirmed that the Inter and Mack B model locks came from the same door lock supplier. Have a close look at the attached pictures and you will see the locks are the same. The red R 190 with the blue lines was a fully imported truck into Australia from USA so you can see the same locks. So try find an International dealer they may likely have NOStock. And those original Inter comfo-vision cabs were fitted to the smaller pick up Inter's such as 110, 120 & 130 etc.

When you called Watt's Mack and asked for a 62QS33 door latch (right-hand) and a 34RC156 tumbler lock set, what did they say ?

I found this interesting and immediately recognized those latches from R model internationals.

Last winter my friend and I restored a 1955 R170, and another interesting thing was the outside push door handles were exactly the same as my R model Macks . So he bought 2 new ones from PAI and they bolted right on . No modifications were needed .
