Forum:

If your Amazon was produced in the '64 - '68 range, and if your seatbacks are original and unmodified, please check these and report on which condition you find (along with Chassis No.). This information will be used to give a better picture of what year and with which chassis seats with tubes began to be fitted by the factory:

Condition 1 - No Headrests, and no receiver tubes in seatback.
Condition 2 - No Headrests installed, but receiver tubes present in seatback.

...if your vehicle was retrofitted with headrests and you know the condition your vehicle was delivered in from the factory, you are welcome to add your info (with explanation) to this survey.

Thanks for participating!
