Dutch,
I have a 55 1st series 3100 with the hydra-matic 4-speed. The option number was R.P.O. 314. I'd like to find out all the build numbers on my truck but there is no one spot for tall the info. I just had to rebuild a couple of linkage pieces (lucky they are forged steel) and now it shifts really well. My transmission expert (an antique himself) says the transmissions are pretty near bullet proof and if serviced will last 100K miles easily.

If you don't drive it, why have it?
