I started the process of getting all the parts I need to replace the rocker panels on my 1963 Impala sport coupe. You would think this would be a straight forward process. Sites advertise complete rocker assemblies, so I should have just been able to pick one of these up and go to town, right! Wrong.
The rocker panel assembly on 1961 to 1964 Impalas is a 4 piece assembly (5 pieces on convertibles) and those complete rocker assemblies that say they include outer and inner pieces are misleading. So I thought I would start a thread to clarify these issues, as I have spent hours online trying to dig up information on this and actually found useful information on the patents filed by GM around this time. I've heard some people say 64 is different, but the parts I ordered say they work for 64 also. If anyone has any info that verifies them different or the same let us know!
I've included some pictures to help people better understand what I am talking about. Sorry about the sheet metal break out being for a 4 door as I have looked high and low for a body shop manual that would show the break out for a 2 door and I happened to luck on this. Apparently if it exists someone is guarding it with their life.
So that piece you bought that says it is a complete assembly with outer and inner rocker is partially true. It includes the outer rocker, but what it calls the inner rocker is actually another piece that should be called the rocker reinforcement panel. Then it gets really confusing when you actually try to order the actual inner rocker as the most online places call this reinforcement piece the inner rocker when sold by itself. Last but not least their is an end cap that also has to be purchased. All and all to replace one rocker you are going to be about $400-$500 in just the sheet metal. Now on convertibles their is also an external Reinforcement that runs along the bottom of the rocker. A lot of people said this piece is not reproduced, but I did actually find them at Hubbards. On a side note, if you are doing a full floor pan replacement with braces it looks like it comes with the true inner rocker attached by looking at the pictures. The full floor pan is actually a heck of a deal for those that need most of it anyway.
Now that I got that all figured out my intention is to actually replace these pieces this summer. I am hoping to get some good pictures of the process and further post on this thread what was discovered during the real world replacement process.
