When I took the cab off of my 77 F150, I realized the cab mounts on the FRAME were eaten up and now I have oddly shaped holes twice the size of what are supposed to be there--no way will the new bushings mount to these. I can't find replacement ones anywhere...if I could, I would just grind off the rivets and bolt the new ones on. Any ideas on where I can buy replacements? I have someone trying to weld new metal in to my originals and cut new holes, but if not done right, that's asking for a lot of new problems. Thanks!!!

 

Bronco Graveyard sells "frame savers" essentially its just a big washer that you weld in the rusted out hole on the cab mount bracket. If you can't weld i would just cut the rivets off the brackets and take them to someone to have the washers welded in. I removed mine to take them to work where i have access to a larger welder than my little millermatic. Here are pictures of mine:

Yep, that's exactly what I have someone trying to fabricate. This looks a lot easier. Thanks!!!!

 

look at my gallery, i bought mine from down south. mtsalvage .com the guys name is mike great guy to deal with. perfect replacements

 

I did the 4 large ones for $4.13! Aren't the "Frame Savers" $8 a piece?!?!

There's a bolt and screw company right across the street from where I work that has EVERYTHING fastener related in stock. I got some perfect washers there. I think they were 3"' o.d. washers is all, plain mild steel and and finish, the center hole is actually a little bit smaller then the stock hole, and bigger then the rubber locating ring on the isolators. And the washers are the same thickness as the frames outriggers.

I weld as a part of my job, and I know when two steel alloys are not welding compatable without following proper procedure. The washers I used and the outriggers are compatable alloys.

McMaster Carr probably has them. For those that don't know, McMaster Carr is an industrial supply company, like Grainger, only MUCH, MUCH better. McMaster Carr has FAR more stuff available and the service and prices are excellent. Their online catalog is exactly the same as their real catalog, page for page, item for item, word for word. The catalog is about 3500 pages long of small print, thin paper, with no glossy BS photos, and a wealth of information given related to each category of items. If you just got the catalog and read it, your I.Q. would go up 30 points in a month.

Don't stick me with Grainger because of the glossy advertisement people. McMaster Carr is superior by far.

Sorry for the aside rant. And I am in no way affiliated with McMaster Carr.

 

I just made my "frame Savers" out of some frame steel i had laying around. Took me about 20 min per side to make and weld in. Used a hole saw to make the new bushing holes.

Nice work! nice welds. Your rust holes were too big for the washers anyway.

 

IS IT HARD TO REPLACE THE REAR CAB MOUNT ON F250 SUPER DUTY 2005 MODEL

 

Ummmm.... ok.

 

Somebody really should start reproducing these, they would make a fortune in no time.

 

I agree. They wouldn't even have to look like the originals, just get the dimensions right and there ya go. People would probably pay a little more if the steel was a little more "beefier" so they don't rust out as much.

 

Or you could just buy non rusted stock ones from us fools here in CA who part these trucks out. I can't tell you how many rust free ones i have scrapped. Now that IO have had 2 people ask for them recently I am starting to save them when I tear down trucks...

 

save the dents dont crushem! :P

 

eh - there's plenty of rust free ones for DIRT cheap out here. I'm not afraid of running out any time soon. Plus sometimes I need parts = I'm fine with being a cannibal, and all the people who buy rust free parts off me usually are as well!

 

^^^^ If guys like me in the rust belt had better means of getting some of those rust free parts, there wouldn't be much left.
