Hello all. First post here as I'm looking for tips, tricks and advice on the topic of a complete floor replacement on my '79 k5.
I'm just starting the process of changing the complete cab floor/body mounts and floor bracing in my '79 and just in a research stage to get some info before i dive in. As I'm getting into it and looking at pictures online I noticed my k5 has none of the floor bracing that goes front to back, and the normal cab mounts are made of 2x4 square tubing. There is also 1x2 tubing running from the front 2x4 tubing cab mount, down the door sill inside the rocker panel connecting to the rear 2x4 crossmember/body mounts.. Also my rocker panels have no inner rockers, they're just wide open. I have all the floor pans to do the entire cab floor minus the transmission tunnel, and I have rear cab mounts. I will have to order some floor bracing and front cab mounts by the looks of things if I want to return it to the factory floor. I'm wondering if people can post pictures of underneath the blazer cabs( inner rockers, floor bracing, back 90 degree passenger footwell edge looking in through the rear wheel well, inner cab corners, ect.) so I can get an idea of where to start.
I'm thinking I'm going to start by cutting out the driver floor entirely and trying to finish the inner rockers. Are the inner rockers supposed to be entirely enclosed to the outer rockers? Can I cut the floor out and weld in a straight piece of steel from the bottom of the outter rocker and pinch weld it to the top edge(door seal lip)?. The floor pans I got don't have the inner rocker on them so I'm hoping I can just weld in flat steel instead of buying inner rockers, and then weld my floor pans to the home-made inner rocker if thatll work?.
I'm also wondering if the front and rear cab mounts weld to the inner rockers aswell as the cab floor? Like I said, there is nothing stock left of the original floor bracing/ cab mounts so I have nothing to go off of... from what I can see, the cab mounts weld to the floor as well as the inner rockers? If this is the case, I will need to start with my inner rockers.. any and all advice from someone who has tackled this job before would be greatly appreciated!
