Ron,
Thanks for the advice. My 18 yr old sister and I spent yesterday morning and afternoon under the truck. We oiled the speedo bushing (hoping it will get us by until I either get the current speedo rebuilt through the firm Jerry recommended (I'm still waiting for a response to my email), or I buy a rebuilt one (found one on eBay for $110). We also installed the voltage reducer, and got the gas gauge working.
The tack is a great idea, especially since I won't have to ruin my dash to do it. I'll check out all three sites you recommended (I could really use it for my '54 AND my stupid Honda Accord Sport Coupe with really-really stupid 17 inch rims and low profile tires . . . I've never known how fast I've been going . . . but I bought the mags and tires because they were "pretty"!!!)
Thanks for helping me out. Since I first posted, we've gotten the truck ready for the road. Putting insurance on it today and hoping to drive it down the road Saturday!!
Kim
