Installing mini-tubs, DSE Quadra Link, and more – Part 2


Progress slowed dramatically the next two days. My son had an appointment Wednesday morning concerning his new job that begins later on December 19th. Once he was back from the appointment, we hauled the new 9″ rear end to my body guy to have it painted. It will be ready next week.

After lunch, we tackled the next item on his list. According to his research, if you install sub-frame connectors, you should also install solid front sub-frame bushings. We purposely raised the car by the rocker panels so we could first loosen and then remove the old bushings. Here is where our forward motion hit the pause mode.

Five of the six mounts had substantial rust damage on the front sub-frame. Enough rust that Matt had to install reinforcing plates. This presented an opportunity for using his new plasma cutter which worked great. After cutting the pieces, drilling the center hole for the bushing and then welded in each plate. Including the time it took to get some necessary parts, most of yesterday and today was spent on this project. This discovery may have caused some of the flexing that he has noticed. Fortunately, the rust was limited to the sub frame area as the body area at each mount was in good shape.

While Matt was doing repairs, I was cleaning up some of the items we had taken off and out of the car. A few years back, he had installed stainless steel fuel lines and an aftermarket fuel tank for his fuel injection. A little scrubbing saw both of them clean up nicely.

Other items needing cleaning was his computer brain, his Alpine amp that had been under the passenger seat, the fuel filter assembly and his seat belts. The rear seat belts cleaned up nicely but the fronts showed some significant wear and he ordered a set to replace them. Probably a good move. All of the belts were had 1969 on the tags.  I also rolled out the pressure washer and cleaned up the old 12 bolt rear end that he is going to put on Craigslist. Since his car is a real SS, it came with this rear end from the factory and is dated January, 1969.

Here are some photos of the bottom of the car with everything removed. Tomorrow we are going to spray the bottom of the car with engine degreaser, let it sit for an hour or so and then use the pressure washer to clean it up as best we can before we begin cutting. Matt and his family are going away for a few days for a much needed vacation. We will resume work the middle of next week, although I will continue to clean up his seats and other sundry items while he is gone.

Messy day today!! We lined the walls with plastic, sprayed the bottom with degreaser and used the high pressure sprayer to clean up the bottom of the car. Matt’s family came over around noon to celebrate a late Thanksgiving.

Back from his brief vacation, we taped the edges of the car for protection, the engineer in my son came forth.  After finding some string for his plumb bob, we proceeded to mark on the garage floor the four reference points on the car.  These measurements will show the relative position of the front subframe to the rear of the car.  Matt wanted to make sure we had a car that was within factory specs before he began cutting it up.  One each side of the car there is a hole near the front body mount and at the rear lower area.  He suspended the bob from each of these holes while I marked the spot on masking tape on the floor.  The measurement should be 54.5″.  Our measurement showed the front subframe to be 1/4″ towards the front of the car and was consistent on both sides.  That was within spec and, at least in Matt’s mind, preferred as moving everthing 1/4″ to the rear would make the engine even closer to the cowl.  So all was well here.

Lots of grunt work being done to make sure we don’t have a fire when we begin cutting.  To that end, we needed to remove the undercoating in the cutting areas as well as others for cosmetic clean up.  Matt bought a power scraper that worked very well in removing most of the undercoating.

To get the rest of it, we began brushing on Aircraft Remover, scraped the areas and then used paper towels to remove the excess.  This did the trick.  Let the cutting begin!!!
