@SCOTI, lol, yeah...

superchevy · 03-02-2021, 08:31 PM

got the drivers door disassembled this evening...tomorrow start on the dash disassembly...little by little

superchevy · 03-03-2021, 09:17 PM

I removed the dash gauge bezel and dash pad this evening...I was going to disassemble the complete dash; gauge pod, radio, steering column, etc, but I realized it would be a waste of time...everything is in near mint condition...pristine even....I can't improve on it...hell, I'm just going to buff the lower dash paint along with the ashtray and glove box and call it done...

superchevy · 03-03-2021, 09:19 PM

more dash pics

superchevy · 03-06-2021, 05:39 PM

damn, I really like the way this one is going to sit....rolled it outside today to power wash the firewall, front frame, crossmember....tomorrow will disassemble the front suspension/steering....then it's frame painting time and a bunch of new parts to install

superchevy · 03-07-2021, 05:09 PM

man, I hate front end work...nasty, greasy, and hard on this old guys back...I'm done for the day....it's Miller time

LT7A · 03-09-2021, 05:58 AM

Might be messy, but it looks like you're winning.

superchevy · 03-09-2021, 09:37 PM

Decided to remove the lower control arm bushings this evening...the drill method is the easiest I've found...going to use Prothane bushings/sleeves, so keeping the existing shells in place...also sprayed down the spindles with oven cleaner to get some of the grease and oil off before blasting/painting.

superchevy · 03-11-2021, 09:19 PM

after soaking in EZ Off oven cleaner for 2 days, I got a chance to power wash some of the greasier front end parts this evening...sprayed on a little Gibbs to slow the flash rust on the machined surfaces...the Prothane control arm bushings showed today too...tomorrow press in the new MOOG ball joints...

superchevy · 03-13-2021, 08:41 AM

I got off work a little early yesterday and finally finished stripping down the front frame...got the brake/fuel lines off...got the steering gearbox off and the master cylinder/booster as well...goal this weekend is to finish cleaning the frame and paint it as well as media blasting a lot of the smaller parts and painting them

superchevy · 03-13-2021, 09:12 PM

Got the new MOOG ball joints pressed in the LCA's....also blasted and painted lots of small parts....tomorrow final clean/paint the front frame and then it's on to installing all the new parts!

LT7A · 03-14-2021, 09:56 AM

It's looking good. You're making quick work of it.

superchevy · 03-14-2021, 12:01 PM

Thank you. I try to do a little bit each day so things keep moving along.

superchevy · 03-14-2021, 05:36 PM

finally got the front half of the frame cleaned/scuffed/painted today...it's almost time to throw a bunch of new parts at this thing

superchevy · 03-16-2021, 07:40 PM

the view you have laying under the cab sanding the frame for paint....also, I've decided not to paint the bottom of the cab...I love the original red primer and overspray...there is so little rust...I'm just going to coat it with Gibbs Brand and leave it as is... not hiding anything on this clean ass truck

1981_c10 · 03-19-2021, 10:33 AM

love the progress!

superchevy · 04-01-2021, 07:54 PM

Thank you. I finally got all the parts in to start to get it back together...got the lower and upper a-arms installed with the new MOOG big block springs...tomorrow evening hoping to get all new steering parts installed along with the sway bar.

superchevy · 04-05-2021, 07:26 AM

Got the new steering and brakes finished up...well mostly, lol

superchevy · 04-05-2021, 07:31 AM

I was now able to set her back down on the ground and add about 800lbs of weight to compress the new big block springs enough so that the upper control arms came off their bump stops and i could torque everything to spec...

superchevy · 04-06-2021, 07:19 AM

not much done today...wheels back off...got the new calipers and brake hoses installed...progress

**Corts60** · 04-06-2021, 07:32 PM

Great work! Man that is one clean cab to start with.

LT7A · 04-07-2021, 08:09 AM

You do very nice work. Very clean installation.

superchevy · 04-10-2021, 05:41 PM

Thanks guys! Yes, this cab is soooo clean...

superchevy · 04-15-2021, 07:00 PM

ok, got some more brake work done...specifically finished running the new InLineTube hard lines front and rear...new brake booster and master cylinder installed...

superchevy · 04-15-2021, 07:02 PM

next up, the big block engine stands and new mounts installed...
