Username Post: '57 rocker panel replace...        (Topic#233589)

I've started replacing the inner and outer rocker panel on the driver side of the '57 today. It's amazing how much more rotted the driver side is than the passenger side. The passenger side only has holes in two braces, otherwise looks fine. The drivers side is a mess. One brace intact, inner rocker almost completely gone, outer rocker is swiss cheese. Of course the bottom fender bolt broke off right away.
One question I have. Is it really necessary to disassenble the most forward part, where the fender bolt attaches? Mine is solid. It looks like I can fold the new rocker around that portion and weld after sandblasing that part. Looks like that's how the factory did it. I'm sure I am missing something here. Any comments welcome.

Thanks.

Over lapping the new rocker flanges over the front of the front bracket, with it still on the car, might work. Thinking about it, the front bracket pieces are spot welded to the front flanges of the old rocker. If you grind off the old rocker metal from the bracket, you can probably overlap the bracket with the new rocker's flanges and weld. The bracket should stay in place for you to do that, as long as it remains attached to the inner rocker side. You probably would have to straighten out the new rocker's flanges so it will slide over the bracket and then bend them back down over it.

Or, you could leave the entire front face of the old rocker on the car with the original flanging intact, cutting the old rocker off just behind the front face edges. Then cut off the front flange metal from the new rocker and butt the new rocker up to the old front front rocker face and weld it together along the corners.

Or if the front few inches of the old rocker are still good, you could even splice the new rocker in further back, leaving the entire front part of the old rocker in position and intact. In that case, I'd cut the old rocker, make some 1" wide strips of sheet metal, and weld them to the inside of the old rocker so that the metal strips create a 1/2" flange around the old rocker's cut opening. Then the new rocker can be overlapped and welded to the flange strips, as well as the old rocker edge.

Thanks for the reply Steve. I'm gonna try to preserve the front part as much as possible, and fold over if I can , and weld. There's alot going on in that front portion, just trying to keep it as simple as possible if I can. Thanks for the tips and suggestions.

Thanks again.

Steve,
After cutting everything apart, I may just go ahead and replace that portion as well. I'll know more when I cut it apart. I can look at it from the inside rocker side, lots of it is sold but I do see a rust hole. I'm guessing after sandblasing it will be weak. Best case would be I'll need to reinforce it. Worst case is I'll get a repro piece and weld the fender bracket onto it.
I'll grab some pictures next weekend when I'm working on it again....

Gary, before you cut apart those front pieces, you should take some location measurements. When you go to put them back together, you'll need to install that lower fender bracket back in the same position it was in. It will have to be the same distance forward in relation to the front end of the rocker and the same distance outboard from the cowl. And up and down too. Basically all 3 dimensions . Otherwise you could have a fender fit problem on the bottom.

Good advice Steve. It would get ugly fast if that fender bracket ended up in the wrong place.

Even with careful measuring, it may be a good idea to place the fender up ther to see if the hole lines up the way it should. You should be fine as long as you're careful in the measuring and placement of the bracket. But it never hurts to verify it with the part that will attach to it. Of course this would mean you need the door and core support installed. If that is not an option, just measure, check and recheck.

Here's what I ended up with. I decided there wasn't enough good metal on the inner bracket to save the front portion so I cut it all out after taking my measurements..

I had that same problem but one side was better, I was able to save one of the reinforcements and bought a new set from East Coast Chevy but sent them back because of poor fit and the $80.00 price
I ended up making my own out of stainless and also did the rockers, I bought new rockers also and those fit very badly, I ended using just the top part and making the rest, you can see how much of the rocker I made and the reinforcement I had left over, I still have these around somewhere, maybe I'll frame them and hang them on the wall

Gary, I'm sure you already know this but you can get an outer rocker panel that already has the fender bracket welded in place. It is the Tiawan made version and it looks pretty good. I'm doing the right side and bought the outer, inner, front floor, toe panel. I took the fender bracket out of the old rocker. I am still fitting them and waiting for it to get a little warmer to finish the project. I went ahead and bought the left side with the bracket installed. After getting into the repairs on the l side I decided to repair that rocker. If you haven't bought your parts I think the rocker with the bracket welded in place would be the way to go. Just my opinion Tom

No, I didn't know that. I bought my drivers side rocker a year or so ago. When I replace the passenger side I may try one of those. Thanks for the heads up!

Has anyone here on CT used these Taiwan outer rocker reproductions yet? If so, how was the fit,location of the pre-welded fender bracket?
