Just a shout out to Rusty at Speedometer Service Co. in Fountain CO. He repaired my deuce speedo and made a special cable to go from the 350 trans to the 32 speedo. Everything worked perfect. When the repair shop got everything installed and hooked up a test drive showed a 1 mile variance between the 32 speedo and the Garmin. Great work, Reasonable price. Highly recommended.
Same, here. I'm still running the cable he made for me over 10 years ago to mate my S/W Wings speedo to my Saginaw 4-speed. I never had it tested, but every time I pass one of those electric signs that tells you how fast you're going, it's dead on.
Another recommendation for Rusty. Aside from doing great repair work for me he's been a phone source for questions I have had.
Here's another vote for Rusty - he rebuilt the speedometer for my '63 Thunderbird and did a great job.
