I've got an old Saab VDO fuel gauge that I'd like to change the gauge face to a more Porsche looking face. Any ideas on how to make your own gauge face that doesnt look like crap after being exposed to sunlight etc?

I'l contact car-bone and see what they can offer.
I measured the Saab gauge today and it is as follows: 10 ohm: low reserve / empty 22 ohm: start of reserve 47 ohm: 50%, middle of range 100 ohm: 60% 150 ohm: 90% 172 ohm: Max on the scale 200 ohm: needle maxed Then I did the same for the stock 914 gauge and got this: 10 ohm: 90% 22 ohm 70% (just below 3/4) 32 ohm 50% 47 ohm 30% 69 ohm Reserve (needle on the R) So the scales are inverted from eachother, one way around this would be to get a VDO gauge and plunder the mechanism as defianty did. When I bought the gas gauge the seller asked if I wanted a Saab temp gauge aswell for the another $5 so I said sure, its not breaking the bank and he wanted to get rid of them both. So after realizing the scales were inverted I had a small stroke of genius. I started testing the Saab temp gauge in the same way and got this result: 10 ohm: needle pegged on max 22 ohm: end of the red area 47 ohm: 50% middle of scale 100 ohm: start of the green area 200 ohm: 20% of the black area 270 ohm: start of the black area So the temp gauge goes the same way as the stock gauge but with a different resolution. Dig up some old electronics books from university and taddaaa... if I connect a 100 ohm resistor in parallell with the sender I will get a pretty good match in the range of the scale from 50% and below.
