Bolts were froze on my 84. cage nuts just spin so I drilled a 3/8 hole for extension thru floor and 5/16 for a punch. Put punch thru cage nut to hold then broke nut loose. Worked well on all 4. Be sure to check that body lines match. Mine did not so had to go back and shim left side of cab 1/2" with large washers. 6mo later had to go back again cause new side step brackets attach to cab mounts. Hope this saves ya some time. fravar

So need to do this, found one old rubber laying on the top of the frame a while back, I can't convince myself to cut into the floorpan though, it's the only damn thing that looks pristine on my truck lol

[emeteriovelasquez]

Your video is the absolute best presentation on the subject of replacing cab mounts that I have seen. I have a question . The cab on my 2000 S-10 shifted driver’s side to passenger side about three quarters of an inch. What is going on with the cab mounts on my truck? Thanks!

[drewdowncutomz]

Do u have a video of alignment of the cab if some of us pulled off the cab completely?

[robertemmons]

Awesome! Since the prior generation C/K series pickups (67-72) are relatively the same, these procedures should work for them as well, at least I'm hoping since I have a '68. I've cut out an opening in the floorboard of a Suburban 1500 in order to access the electric fuel pump so that i didn't have to empty the fuel or drop the tank. But I've never thought of cutting an access for a bad nut. I like it! 👍

To add, for those who didn't know this. At the 9:16 mark, when replacing that bushing it might be a good idea to have a look at the ground strap and replace it as needed since bad grounds can cause electrical issues.

Thanks for another great video David!

Great video! I have a 1981 K 10 and I’m having a problem with my gas tanks I believe it’s the vent hose and that’s it’s possible clogged. Anyway you guys can do a video on it or possibly how to remove the gas tank and clean everything out that would be great thanks! Jack

Does the 2001 Silverado have a cage but in the floorboard too? I got a broken off bolt can I just sawzall it outta there?

Hi Dave Yup I am in NH. I am 62 yr;s old. I have been staying on the road doing my own stuff since 1975. I have to get on it with the 1986 K30 cab mounts. My brackets are still all there. I needed to see your vid cutting the hole. I dont have a lift but The part you said dont jack from that is angeld is what I need to replace. I am fresh out of bed rails. What do you think.

[Tommystaven]

Any tips for replacing the cab floor braces both the one that goes to the rocker/ kick panel and the main support channel on my 73 are in bad shape and I have the replacements just trying to figure out how to do it before I just dive in

[maxkling]

Is there a way to do it by taking the cab braces ? I have to replace them anyway if not I’m going to sawzall through my bushings, don’t want to cut through my floor

[nickwilliams]

If you’d cut the bolt then you’d still have to cut the floor to get the rest out?
