I had it going into a '91 F150. The ZFs were ran in the 3/4+ ton trucks from I think the early 90's until about '97. Couldn't tell you how it'd fit in a '66. I'd think it could fit... Hell, if your in Byron you could just come down and take measurements to help out. I'm in Warner Robins not too far off exit 144.

Oh and the price is dropping down to $1000 from the 1250 I originally had up, did some research and that was too high.
