1970 L-78 Nova Restoration; Saga of The Green Bastard

[L78_Nova]

With the car up on the rotisserie it is easier to access for welding. You can see where I have ground down the welds and cut out the overlap of two ribs.



Ready to plug weld to the quarter bottom









And all ground/cleaned up. I was very happy with how this turned out. Looks exactly as the original.

LH side. The patch was only on the forward section this side.
Sorry no welded pictures.

Well, back to travelling for work (first time since March 2020) so it's been a super busy couple weeks. This is looking into my back yard before I left Feb 27th. We are 3rd for snow accumulation since they started keeping records in the 1870's.



So it was a nice break to arrive in Nebraska to this ! Highs of 70 - 80 for 4 days. Unfortunately they desperately need moisture.



Back to the program... The rear underbody at the back bumper was a little torn up. I suspect from chain hooks from towing or trailering. I have before pictures from the left side .





And... After pictures from the Right side. Both were roughly the same condition to start. Right side needed a little segment of a washer welded in to replace a torn out piece.

Having some previous experience with Novas, I know where to probe for potential rust problems. The forward fuel tank brackets are susceptible to road spray and it is common for the trunk floor to get soft spots above the tank brace where moisture and dirt accumulates between the sandwiched layers. The metal rusts and swells so to fix it properly it needs to be cut out from both sides. The underbraces are heavier so easiest to start here.











Sorry, only one poor picture of the finished patches. Lots of work to fix a few tiny perforations. The patches are the extreme left side of this photo.

Same repair from the trunk side.
Pinholes picked open



I used a punch from the bottom side in the corners of the cut out hole to mark where I needed to cut the top side out.

Rear window channel. Right side of rear window channel was a little rough... a little too far gone to use the old JB Weld trick.

I made patches from scrap with pre-bent edge for two reasons. First, the break along the edge better resists warping. Second, in some places the pits were all the way around the edge.

I didn't have a piece the perfect width so I did this in two halves.

Top side cut open



Here you can see how rough the lower edge was. This will be cut out later.





Top side welded in. Bottom edge has now been cut out.







Fitting the lower side patch. Here you can see the shape I used. Had to use two pieces on the bottom (depleted my scrap pile)



First bottom piece welded in



Little bit left to go... put the camera away too early... sorry.



Also made a couple small patches to the face of the channel further to the left, no pics

Nice work in the trunk and the jamb areas. Saw the pics you posted of the snow you guys have been getting this year. That is just crazy. Hopefully, it's a slow melt for the region this spring.

Keep up the great work on the Nova.

Found a picture of the finished rear lower window channel. You can see a few other areas had some work and the trim brackets are reinstalled.

It was around this time I began cleaning the underside of the car. Primarily using a drill and wire wheels. Didn't take too many photos of this... pretty boring, tedious work.

Most of it looked like this to start





And something like this after. lots of hammer and dolly work taking out little dents here and there at the same time.

Finishing the underside of the drivers floor pan, shifter hole and toe board repair.
