The dash as you said was a write off. I am restructuring and resurfacing it. So far I have rebuilt the majority of what was wrong with it. The fiberglass has turned out much rougher than I hoped but I can just put a thin coat of resin on it to smooth it out. Then sand it down. I plan on doing a light texture and paint it black. Suede would be amazing unfortunately way above my skill level and out of my price range. If my dash doesn't turn out the way I want perhaps I'll pm you about one of yours. From what I've seen most good dashes get well over $700. I've got $140 in this repair.

im not trying to doscourage you, but resin is the "glue" that holds the glass together and is a absolute PITA to sand.

If you want to make smooth fiberglass parts the best would be to smooth out your dash and then make a mold, using gelcoat. then make a "cap" using gelcoat as well. Then it would be UV resistant and you woudl have a nice smooth surface. But intergrated that into the stock dash would be difficult. You can see where Im going with this. Really if youre trying to just smooth out the dash, id use bondo... although I dont know how that would stick to the vinyl dash surface.

Wedge. I work in car audio so I do have experience with fiberglass. I know it's a few hours of sanding away from looking exactly how I want.

 

240zdan. I'm trying to avoid bondo. I fear that it won't flex and would just flake off or crack. I don't have the means to make an entire dash mould. One of my installers did this for a living before working here and we are doing this project together so I'm following his lead on this one.

Got some rims for free. Didnt mount them yet but put 1 next to the car. Please give your honest opinion. Im kinda up in the air as to if I like them or if they fit in with the look of the car.

slowly working on it. I spent a couple hours finishing wiring the car. I relocated the relays to under the dash. I have also been spending time refinishing the floor pans, trans tunnel and firewall. I have been peeling the old sound deadening off the car. wire wheeling and rust encapsulating the car. When any actual progress occurs I will let you know.

Hey man, fantastic build you got going! I have enjoyed reading your progress with your build and I am envious! Hey If you are still working on your dash I have an idea if you have not found a solution for it yet. There is a member on this forum that has a dash that is wrapped in some kind of fabric. I think it is leather and it looks amazing! I once considered throwing out my dash and building a custom fiberglass one until I came across this one. Well It may have been a different one but this is still really nice. Btw, how is your build going now?

Edit: oops, my bad, I just realized that you posted this a week ago. When you get some progress let us know!

4.6 that is one of my all time favorite dash boards. I have drooled over the idea for a while. Unfortunately it is out of my current budget. I have been working on the car getting it ready. I have been tinkering with the wiring trying to get it all working. Im gonna need to update my wiring guide. I was having issues with the front parking lights coming on when I hit the brakes. I got the remainder of the original sound deadening off the floor pans. I wire wheeled them clean, rust encapsulated them, then put some dynamat down. I also used some fiberbondo to smooth the dash and then some resin as to smooth it even further. Im gonna post some pics of some of teh progress.

Ill look at the resins when I go back to work on Saturday.

 

Quick question. I have my fuel pump relays all wired up and and on my ezwiring harness there is a fuel pump wire. I have that wire set to open the gate on the relays. For some reason it has 12 volts when in the on position but it stops sending 12v when I turn the key to the start position. Is this going to be a problem? Wouldnt I need the pumps to be running when Im trying to turn over the car.

I called ezwiring and they said to connect the ign accessory and the ign starter together. I decided I didnt want to do that. I dont want my radio and guages and all my electronics on when cranking. I cut the fuel pump wire on the back of the fuse box and wired it to a wire that gets power in the on and start position. I wont get any fuel in acc but thats ok. Having a troubling time with the horns not working properly but no big deal.
