Title: How is Master Cyl cover plate fastened to tub?
Post by: squidtone on May 17, 2017, 10:21:40 PM: I'm going through putting everything together in this ol' '50 Jeep and I'm a bit baffled on how the master cylinder cover plate was put on. Were there captive nuts in the tub for the fasteners to hold the plate on?
And secondly, my tub seems to have had only 3 holes for this plate. The plate has 5 holes. Did Willys economize by 1950 and only use 3 fasteners on the 5 hole plate?
Thanks!

I do not remember what i used to fasten the plate....maybe tinnerman clips?

The 2A tubs Iï¿½ve messed with have caged 1/4-20 nuts in five spots.

You can sort of see the caged nuts here.ï¿½ This is a 2A cowl area that was ï¿½joined/turned intoï¿½ a 3A tub.

These are just observations.ï¿½ I don't know what is "correct".

The bean counters probably saved a few pennies for that change from the 5 weldnuts on the '2A. 55, that's a good idea, i'll try those "U" clips/tinnerman with some sheet metal screws. The existing holes show no signs of sheet metal screws "threading" the holes, so I don't know how the fasteners stuck in there.

Post by: aboyandhisdog on May 20, 2017, 05:25:24 PM: Hmmm...a quick perusal of my Kaiser Willys catalog shows the plate having 4 holes for the 2a and 3a. It shows the MB and GPW having 5 holes, and doesn't show one with 3 holes at all. My m38 tub has the 4 hole cover and the nuts are what I guess would be called "weld nuts" as they are a part of the tub and fasten with what I believe to be 1/4 inch bolts.
