Core Support

I was thinking the next step was the doors, but changed my mind and went to work on the core support. I am using a core support out of an '89 gasser (the one that donated its firewall and dash/heater). The only mod I had to make to put the '89 core support on the '77 frame was drilling two holes for the mounts. The holes in the frame were about 2 inches farther apart than the holes in the core support. I chose to drill the frame rather than the support. I figured it did not matter and the frame would stay put while I drilled. In this picture you can see the 1 1/2 in. spacers for the body lift below the support.
In this shot you can see that I still have work to do on the brake booster/master cylinder. I thought I was going to use the booster out of the '89 so I left it on the firewall, but as it turns out, I need to use the one that came on my cummins donor because the port size is different and I need to use the bigger plug to plumb in the heater controls. I considered tapping into the vacuum system elswhere, but I am not sure if the vacuum pump on the cummins needs a special booster or not. Anyway, five bolts and it will be changed. It is easy to get to with the dash out.
On the passenger side, I wnt ahead and put in the inner fender. Other than someday replacing the turbo housing and/or upgrading the exhaust, very little work will need to go on on this side of the engine. I will most likely need to move the radiatoor overflow bottle toward the headlight in order to run the intercooler pipes.
Next up, radiator.
