Gentlemen...I have an internal GM document (3 original mimeos, exactly) that state within the 1954 production year, 6% of the vehicles (not cars and stuff, but trucks) were hydra-matics. This includes pickups, burbs, etc. (I'm lucky enough to have a 54 Chevy pickup and 54 Chevy Suburban---both with hydramatics.) On the list is broken down 3-speeds, 3-speed Heavy-Duty, 4-speed floor shift. I recall this is for Chevy only, since it's not in front of me, but I'm not sure. Hope that helps for the 54s, anyway! A bit off strictly hydramatic thread, but has anyone heard of the someone reproducing the 2-tone checkerboard cloth seat material, as found in some hydramatics? Or this same material in Hydramatic Burbs? Thanks, and cheers!
