I am about to type my new service parts id sticker for the glove box door. On the original glove box door it's easy to read one of the codes but hard to read the description. It looks like 4M38AB - 4M???B Turbo Hydromatic but on the invoice it reads 4M49AB Turbo Hydromatic. It almost looks like the invoice number and desc. are in the desc. of the label but with a different code (4M38AB). Does that mean it had a base turbo with some change or something?
ALso, I can read what is in the "W/BASE" or the"SE" section. What goes in there for my 69 C10, 350 engine, auto, A/C, SWB?.
