Getting rid of the T-Tops




Now that we have got the car home and assessed what is needed we have made plans for the stages of the build. The first thing we have addressed is the fact that the car is a T-top car. T-top cars are not eligible in that form to race in CMC. We found a 92 firebird parts car that was a hardtop. With this $150 parts car we got a good Formula hood and one good door and two good fenders. These are some good pieces to have if you have three guys all running the same type of car. Most importantly we got a good hardtop that we could cut off and graft onto the CMC car.
So we have cut the top off the parts car with plenty of extra sheet metal on the A and B pillars and we removed the reinforcement panels on the A and B pillars with a spot weld cutting tool. (Harbor Freight 5 bucks) By removing these panels on the race car and the donor car we can weld the new top on the race car and get weld all way around the graft area and then the reinforcement panels will be installed by spot welding it just like the factory. By doing it this way the joint will be no stronger or no weaker than the factory joint. Photos will follow that will better explain this procedure.
But before we cut the top off the Race car we are going to bend the main hoop and install the A pillar bars and the upper cross bar for the roll cage. By doing this we can get the cage tight to the roof. Then when we cut the roof off the car we can easily get the 360° welds that are required per NASA rules. Then we will install the non-T-top roof from our donor car. Our plan is to document this well so anybody with a saws-all, spot weld drill, tape measure and welder will be able to do this at home.
The plan for this Thursday(Mar26) is to remove the reinforcement panels on the race car just like We did on the donor car and remove the instrument panel to clear the way for the roll cage. Then we will begin bending the tubing…stay tuned.

  1. Cool, keep the pictures coming. I have an '89 Formula that I'm putting a full cage in this winter.
