78 gmc Heavy Half - rebirth
« on: February 21, 2017, 12:02:31 PM »
rebuilt over the last 2ish years, my 79 was falling apart from the salt and rust, and being daily driven for 8 years, so decided to go for it and do a full rebuild:

started with a solid frame, resurfaced and painted black,  you can see the shine on the crossmember. had a buddy with a hi-ab crane lift the cab to go back on the frame, saved a lot of effort.

dad made a bed lift frame for the engine hoist, worked great to get it off the front edge and back on the frame, the bed is rust free- was a great find up here. also shown is the electric fans from a windstar van that i now have on toggle switches in the ashtray, for on/off with temp, and both on. also realized how hard it is to replace the front header panel with the bed mounted, was a bad choice..... will do it off the truck if i have to again lol.

made some brackets for a 75 grill to fit the 78 rad support, they work great. Also nabbed a set of 68-72 gmc fender badges to out on, love the look of them. also pictured is the interior from the 79 truck from before.

here is the tach/fuel combo gauge installed, works perfect and allows for a trans temp gauge in the dummy spot on the side,.

then i found the cab rust.... from tar paper sound deadener and paint, i didn't find until i started sanding for paint, so back on the grinder to get rid of the cancer. took way longer then i wanted, as i can only work on it on saturdays.

Started final sprint for painting, sealer primer and high build, and alot of sanding, as expected, the last 10% takes the longest...
also stirring up the light quasar blue metallic, mesmerizing

the filter shows what lungs would look like. please wear a mask when painting!

fresh out of the booth and getting ready for reassembly. also decided way too late to not use some bed holes, so i used red fender washers and stainless bolts, they look good enough and will serve as a reminder to make up my mind before the paint hits a gun....
