The cover and all of the foam is now removed from the seat bottom. The sides are crooked as a dog's hind leg. The bottom is going to require a lot of work.
I have looked at photos of the back seat in other 41 - 48 Chevs. They all looked like they were deeper (front to back) than the base would allow. Additionally, the Chrysler seat was too deep for the base and I figured I would have to cut it that way as well as the width. Then I remembered a piece that came with the car. I drug it out and sure enough, it fits in front of the base, extending it out. Now it is too deep. I need to get some advice from Dan Two Lakes!
The piece is going to need rebuilt or replaced. Three of the stand offs which are supposed to attach to the base are rusted out. I will be glad when the interior work is done!
Back at it. Made the extension and the bracket. It was all welded together. Holes were drilled through the lower brace. Rivnuts were installed. The back still needs some minor tweaking, but it mounts up solid.
After some measurements were made, the entire cover and foam was removed from the bottom. It must be narrowed, have the depth decreased, and the seat raised.
The AC guy was able to get free and come over today. He spent a lot of time looking it over and giving me some pointers on the install. Left a couple of pieces of hose so I can verify routing. Thanks Chris.
The good news is that the positioning was OK. So, I quit working on the back seat (did I mention is dislike working on interior items?).
I had to make a bracket for the motor support. It attached nicely to the top right firewall pad bolt.
The center back bracket posed a bit more of a challenge. I finally decided to make a 90 deg. bend in the very top of the VA supplied bracket. I then located where the hole in the bracket would be on the cowl vent opening. The flange was flattened with a hammer and dolly. The hole was drilled. A 1/4" x 1" bolt was dropped in and welded to the body.
Finally, the two brackets on the front had the holes drilled. The brackets were installed. This baby is solid!
The lower mounts were straightened, cut, and welded back together. The stock bottom clips on the body were cut away to clear the modified mounts. These hit the boxed in brace on the floor directly behind the brace. I may get a nut-sert tool and inserts for these mounts.
I made one bracket for the top mount since I was not sure if this mounting arrangement would work. The seat back was mocked up one more time in the car. This time it was centered better in an attempt to determine its final resting place. Unfortunately, the bracket ended up half floating in space. A filler panel was made and welded into place. Finally, the seat back was installed and centered one more time. The location of the bracket was marked. A little weld through primer and the driver's side is finished. Looks good. I need to make the parts for the right side.
When I bought the car, it only came with the back seat back. The front seat and the back seat bottom were long gone. The back seat back was close to gone.
When I bought the front seats, the back seat from the car they were out of came with the deal. The whole deal was so cheap, the back seat was gravy. But it was too wide. I figured if I completely destroyed it by modifying it, I was only out my time.
So, today I started cutting down the seat back.
2" had to be removed from the top and a whopping 9-1/2" had to be removed from the bottom. The side pieces had to have curves created to clear the wheel housings.
In addition to the cutting, welding, and grinding, a great deal of time was spent on the shrinker and stretcher. Some of the parts were also manipulated with heat from the torch.
At the end of the day, it fit pretty good. The springs still need a little tweaking. There are some spring clips which still need to be reinstalled. The lower mount brackets need to be shortened and the top mount brackets need pockets built and welded to the car. Hopefully the upholsterer will be able to make covers without a pattern. I am keeping the stock covers to provide a starting point. For the most part, I think they will work. The bottom will be next up.
