73 POLARIS E3 BUILD...Slowly..

So close to paint!! A few small areas to reprime and sand with 600…then I decided to do the front subframe stiffening triangles. I can’t help adding more work..lol. I cut them, bent them and set in place. I just need to weld in some chases for fuel line, etc..and they’ll be ready to burn in!View attachment 220228View attachment 220227Tip
 
advice: make a hole in it for inspection and to paint the inside after the welding activities.
And don’t forget the holes for the fuel lines.

100%. I'm going to use a steel tube to weld in place for passing fuel line through..or anything else that may be needed. I'll also spray with weld through zinc primer before and use a chassis rail coating on the inside..
I figure I'll never have this opportunity again to add stiffening like this. I did the diff support upgrade, too..
 
I am still undecided whether to make something like this myself or leave the original. Would it really make much of a difference for the car I am restoring? I think the weakest part is the missing B pilar connected to the roof. Very frangible car. And after all, it won't be a car to race.

I would say, if the plan isn’t to add much more hp and push it hard, then no, probably not important to do. I’ve just been dragging my feet for so long on my project, and now that I’m finally pushing again, I want to make sure I don’t regret not doing something when I had the opportunity..easy to do while it’s at this stage..:-)
 
-slots in the frame rails welded closed
-zinc primed underneath
-welded in the angles
-welded in stainless tubes for lines to go through
-zinc primed again
-seam sealed everything for good measure
Frame rails and sills will get internal coatings, too.

I think that should be pretty solid. I have nothing to compare the rigidity to from before, but I hope it helps a bit..that and the diff support welded in place seem like good ‘while I’m in there’ mods..

I’m down to needing to sand the hood and trunk, then I’m ready for paint!

Thanks! I had been reading about those little triangles and figured why not…
I also am looking forward to my paint process…. I’ll be sure to document the whole thing here. It’ll be in my garage…
