Many years ago I had two-seater Tbirds and I have a couple of manuals lying around that are no longer of any use to me.
I will give them (free) to anybody willing cover the postage that it would take to send them.
1956 Thunderbird Electrical Equipment Installation - Most pages are in 11 x 17 format.
1955 Thunderbird Specifications - Drawings and dimensions - Some pages are in 11 x 17 format.
