My Cab Mount is gone - The 1947 - Present Chevrolet & GMC Truck Message Board Network

spavinaw · 05-31-2010, 05:23 PM

My driver side rear cab mount is gone. Rusted almost completely away. I have cut out most of it. I dont have the experience or $$$ to get it fixed. What will it hurt to leave it like it is?

8mpg · 05-31-2010, 08:52 PM

you can buy a new cab mount from *****************

They are not that expensive. Best off fixing it right the first time.

ray_mcavoy · 05-31-2010, 09:05 PM

Hi spavinaw,

Got any pics of the damage? I'd be worried about the cab sagging in that corner and messing up the shape of the door opening.

That's pretty much what happened with my 77 GMC plow truck. The front driver side cab mount support (and floor above it) is pretty much gone. The whole cab leans forward a bit and the door opening is all jacked out of shape so the weatherstripping doesn't even touch the door in places. The missing cab mount transferred a lot of the load onto the front fender. That caused a chunk of the cowl area to crack and break around the fender mounting holes.

So what I'm getting at is don't just leave it. It'll eventually cause more problems. Even if you don't have the means to fix it correctly, at least rig up something to support the weight of the cab in that corner.

spavinaw · 05-31-2010, 09:33 PM

Thanks for the input. It sounds as if i need to address it now. So, what does this require or how extensive of a repair is this? Will it require removing the cab? Or can it be done without removing. Thanks for the input!

8mpg · 05-31-2010, 10:09 PM

You can buy the supports here:
http://www.*****************/-63-87-f...hassis-mount-3

It would be a lot easier with the cab off, but I think you might be able to do it with the cab on IF you have an air chisel. You will need to knock out the stock rivets, then just slide the bracket in and bolt in the new one.

spavinaw · 05-31-2010, 10:19 PM

Ok. I guess I am wrong on what part I thought was a cab mount. Mine may still need replaced but these are not what I was thinking of. Let me do more research and I will get back with my question. Sorry but thinks for the info and link to the new cab mounts.

71swb4x4 · 05-31-2010, 10:21 PM

Is this what you need? http://www.gmcpauls.com/pictures/rearcabsupport.jpg

I do beleive it is. Now, can someone tell a begginer what it takes to replace these? Please? Just a quick overview would be good.

my1st69 · 06-01-2010, 12:56 PM

I am in on this i want to learn if i ever have to do it
Can someone also please post a pic of the full underside and show where all the mounts are?

**michael bustamante** · 06-01-2010, 05:41 PM

theyre cab supports right? Im subscribing as my 2 driver sides are rusted thru

spavinaw · 06-01-2010, 05:43 PM

I beleive what we are now talking about are the rear cab mounts or supports? I hope some experienced guys or gals jump on this. It appears to have a lot of interest already.

RustyDan · 06-01-2010, 10:50 PM

Good thread...My truck is rusted bad underneath. Utah salted roads.
I have TWO cab supports going away. Thought I'd have to wait to pull cab as well.
Maybe not. I'm getting optimistic, We can do it!
Thanks man

oldblue1968chevy · 06-01-2010, 11:03 PM

LOL mines torn down (rocker cab corner etc off) its not gonna be too bad (i hope).
Cut off just this side of the mount (where its solid to weld) weld on and weld/bolt the other side

. Now I havent done this yet im just guessing..check my build there may be some pics in there idk

my1st69 · 06-02-2010, 01:25 AM

can you guys post some pics

JimKshortstep4x4 · 06-02-2010, 05:20 AM

Here is a picture of the cab floor with the sheet metal mounts intact.

**LockDoc** · 06-02-2010, 07:30 AM

-
I believe there are two different styles of replacement metal cab supports, one is welded on and the other bolts on over the old support....

LockDoc

oldblue1968chevy · 06-02-2010, 09:18 AM

So the diff. would be how many holes, and which one is preferred lockdoc?

Depends on what a person is doing with the truck. Over the top could be for a temp fix or a driver and the cut out and weld in the new for a correct rebuild... That's just my opinion though...

oldblue1968chevy · 06-02-2010, 09:31 AM

If im spending this much time and money on rust repair im doing it and NEVER doing it again lol

so the right way is to cut em out and weld em back (no screwing)

spavinaw · 06-02-2010, 10:05 AM

Does the cab have to be removed for both of them?

**71blksuper4x4** · 06-02-2010, 10:14 AM

I definitely recommend removing the cab if you are repairing this. If you atleast jack up the cab off of the frame, you maybe able to use the slip on cab supports. The best way to weld them in, is to remove the cab and lay it on it's back like how the cab is in the pic above. Also, I 100% agree with Leon, the slip on is a quick repair that is prone to rusting out again, as you are just "Band-aiding" over rust. The weld in is a more permanent fix and would look more original if that's what you are looking for. Either way, you need cab supports to keep the body level, and to be safe on the road. Trevor

Quackaddict · 06-02-2010, 10:24 AM

I am another in the long line of cab support replacement dudes. Funny thing is my passenger side is fine and my drivers sides are BAD. I was gonna cut out the rusted out parts, POR-15 what is left and then get the slip on replacements and weld them on. My truck is going to be a driver but I want to get the problem fixed.

oldblue1968chevy · 06-02-2010, 11:16 AM

thats probably why my cab feels like it tilts 2 ft side to side lol

my67chevytruck · 06-02-2010, 11:43 AM

I agree with Leon, and Trevor, get the weld in replacement piece vs. the slip on's

mr48chev · 06-02-2010, 12:01 PM

Wes (here on the board) has them in his catalog http://www.classicheartbeat.com/cata...%20Support.htm
http://www.classicheartbeat.com/products1.htm

Sometimes it's better to call him than email him though but from experience if you get the online order in early enough it goes out the same day you order it.
