First off, nice rig and love the colors! How is the interior....I assume great?!? Although it may indicate 55k, are you sure it's not 155k? Any Carfax to document the mileage?
My 89' was actually 300k+. I figured out the mileage after tracking all the mileage readings throughout it's life on Carfax. Once I figured it out, I then converted my 89' cable driven speedo to the 90-91 electric speedo. With an adjustable DRAC unit, I'm able to get my speedo spot on!! Tire changes, gear changes, etc...fully adjustable plus an extra digit for the 100k counter.
Just an idea for you.
