Anyone familiar with Daytonas?

The speedo came and went on my 87. I replaced the S/D sensor but didn't help; next I disassembled the speedo itself to find one of the gears stripped. At the time somebody was making replacement gears for sale on the net.

I never had any trouble with the turbo's on my cars. Or head gaskets.

The control unit for the headlights tends to go bad and are hard to find, last time I checked.

I don't see any problem with replacing one bad piston on a stock rebuild, as long as the cause of the problem was corrected.
