Hard Cab Top

EDI · Post by **EDI** » Tue Dec 04, 2007 6:15 pm

I have a hard top with the rear window being oval. Is there a standard configeration for parts for the window gaskets and replacement wood.

Just to be more specific the window gasket and wood I am referring to is for the frame to go around the door windows

Was yours a roundish foam with a flat part that was bolted in by a metal strip, and everything covered hin a thick fabric with metal wire in it? If so thats how mine was, but no one seems to have heard of that (I am still looking for something good to use..)

I have a hard top on mine but it has the rectangle rear window.
I do not see any wood around the door frame on mine (or wood anywhere else for that matter).

Can you explain about this wood?

Also, I keep hearing about J bolts to hold the hard top on. I do not have these and can not figure out where they would go. Can someone explain and perhaps post a pic?
Thanks
Hal

The wood pieces are part of the adapter kit that makes the CCKW top fit an M37.

My cab top is metal, the oval window is held in by a rubber gasket. A mounting bracket is used to bolt onto the windshield frame using the same bolt holes that the canvas top brackets use, then the top bolts onto the bracket. The bottom of the cab top has a channel that matches up to the cab and bolts on. The wood runs on the two sides of the door window with it looks like a metal plate that would hold a gasket. Also on top above the door windows there is a drip channel that runs laterally across the window then down the side of the window. Tommorow I will try to post a couple of pictures.

This is my first winter with this truck, so far I have already towed 3 other trucks out of the ditch and I haven't even come close of getting it stuck.

Hey Hal, How's Tricks,
There are actually 2 "J" bolts & 2 "U". Which goes on the first I am not sure at this point? They mount on the bow-pipe & anchor it to the vehicle on either side, just inside the rear most pilar. Field made metal tops utilized the bow, at least mine did, the factory made tops, I think didn't?

Seasons Greetings To All,

Charles:
Thank you, that clears that up.

Bruce:
we are doing well, thanks. How about you folks?
It is getting a bit chilly up here....

On the U bolts, I have 2 of them and it is clear where they go.
As I understand your post I do not need the J bolts since I have a factory made hard top. Is that correct? If not I am still puzzled as to where the J bolts would go. Can you post a pic or describe where in relation to the U bolts they would go?

Thanks
Hal

I'll get some fotos today. My bolts are not installed, I found them in the glove and didn't realize what they were until I already had the rag top installed.
I think the post itself has indents for a secure fitting/mounting, Charles, is that correct? I am battling a sinus infection, three rounds of antibiotics so far. A cat scan is next??

Yes, the indents are part of the canvas top harware & the original arctic hard top with the rectangular sliding rear window. The CCKW top with the oval rear window doesn't utilize the same installation set up, it bolts to the top of the windshield frame & across the back of the cab.

Hal I added this link to "installing a new soft-top". The link should let you access my album and the rest of the pictures of the head-ache rack.

Charles,

I noticed you referred to a CCKW top, what does the CCKW stand for? I just bought the truck over the summer and still learning the different parts/nomenclature for the M37.

Thanks,

Ed

CCKW is a different type of WWII vehicle i think

When I got my m37 it had a top with a oval back window in the bed. When I tried to mount it it was about 3 inches to short to reach the windshield frame. I made a piece by breaking a piece of 14 gauge metal and making an adaptor. It turned out great but I know it is not the right top, it fits around the tub but was not right with the windshield. I have been told that the top I have is a CCKW which was for a WWII era 2 1/2 ton. It looks like it could be that old. Anyway it keeps the rain out.

A CCKW is a world war II vintage GMC 2 1/2 ton truck. Evidently there were many hard tops for them on hand when the trucks were phased out of service. The hole pattern across the top of the windshield frame is exact with the M37, they fabricated pieces to fill the gap at the bottom on each side as they aren't quite as wide across the back. The wood strips fit it to the back side of the door glass & the rain gutters over the windows make that area wide enough there. With the proper fitting adapters in these areas, they actually do quite well. I will be the first to tell you though they don't fit like an original arctic top & never will no matter what you do. It's simply a will fit deal where there were lots of them on hand, so they got used as such. If you want a really nice fitting hard top, 2 options exist, the original artic top, or the fiberglass reproduction tops from Snake River 4X4. Tom Howell of Snake River post here, so you can contact him easily. The fiberglass tops from Vintage Power Wagons don't get it when compared to Tom's reproduction, nowhere near as nice & much harder to install.
