Are you putting msd? If you are then I would grab a charger specialties tac.
If you want to refresh your cluster that is easy..
I have some tips for you..
First the "glass" McGuire #17 and #10 cleaner and polish, I wont go into great detail like I normally do, but its easy to use, clean it with the cleaner, polish it with the polish, if there are scratches I use some 2500 dry to get rid of the scratches, then wet the 2500 and finish with 4000 wet. This stuff works on all your brake and marker lenses too... amazing stuff, sometimes hard to find..
Next I would get the decals from
http://www.ebay.com/itm/68-70-Road-...989598?hash=item2a6b03115e:g:vCcAAOxyyUtScXnT I have his email somewhere, but easy enough to buy them on ebay. Them are nice and thick and really easy to put on, hardest part is taking off your speedo needle and its easy with this tool I made (get an old table spoon, cut a small line in the end of the spoons that the pin can go through it and use it like a rocking puller).
For the odometer rolls Amie at
[email protected]
she sells the odometer rolls for $15 (they were on sale for $10 last time I bought them), and she sells the lens kits witht eh brake system lens the little green circles for the turn signals, for like $15, and she also makes some cool black half circles for the bottom of the needles, they bring out the needle nice..
I also bought my needle paint from her, not sure if they still sell it, but most of the time the needles are still bright, but if they aren't or you want a different color, she has them...
She sells faces too, but she used to only do white. I used them a couple times on protouring cars, and they are nice quality, but for anything you want to resemble original not going to cut it..
As far as the black decals go, if you ever tried the other kits, you will LOVE his kits listed above for $22, they aren't perfect like the little rivits at the bottom get covered up, BUT they go on nice, easy to deal with and you wont throw 3 sets away and beat up your neighbors wife in anger trying to get it done. They go on easy, stand up well, and look nice... Great for a drive to the show car...
Now that takes care of your gauges, lenses, and "glass", if you had a cluster that ran well that's all you should really have, I would definitely switch to led lights
https://www.amazon.com/LUYED-Bright...018LUUON8/ref=cm_cr_arp_d_product_top?ie=UTF8
that's a 5 pack I think I bought them in a 20 pack for $25, but they are normal 1895/57 bulbs but led instead...
Last would be your chrome knobs, I mean really no cheap way to do them, PG sells the kits for around $120 with all new chrome knobs and its worth it, because to send them out will be $250, lol..
If that is not in the cards for your wallet (I'm not saying you don't have $120, but I know how it is restoring a car, its expensive and that $120 can be better spent other places. I would buy a can of spaz stix mirror chrome (stuff isn't chrome, but will impress you).
https://www.amazon.com/Ultimate-Cle...42842&sr=1-1&keywords=spaz+stix+mirror+chrome
you don't put that over primer you put it over super shiny black
https://www.amazon.com/GLOSS-BLACK-...3080&sr=1-1&keywords=model+master+gloss+black
I clean the buttons, scour them with scotch brite pads so they are smooth, sand them, clean them with sem soap, spray them with sem 39863 promotor, then hit them with the model master gloss, let that setup and then spray the spaz stix chrome, coat them up nice and then buff them out with some soft cotton...
NOW, if you have to buy, sem soap, 39863, mm glass black, and the spaz stix, and a cotton cloth, and a scour pad, just to do your buttons, it wont be much more money to just buy new buttons, BUT keep in mind, the chrome paint will also do your heater control and anything else you need done, sem soap is great for washing your grills, bezels, kick panels, anyting plastic you want to paint that may have had armor all or silicone of any kind on it, and that bottle lasts a long time. And same with the sem promotor, its a big can so you can do an entire car with that can (all the plastic anyway, grills, kicks, pillars, bezels, seat backs, etc)...
Besides that stuff, I just use a can of electrosolve contact cleaner (I know they all say no residue, but this stuff means it), and compressed air to clean all the switches and gauges out, to test them I plug them into the gtx, lol..
So hope that helps you, all of them products will surprise you, the mcguires should have its own tv show it works so well on plastic lenses, the chrome paint is better than you will expect but still not new chrome obviously, it will look like 5 year old chrome or chrome on the interior of a Hyundai before they got expensive.
Good luck
