Hi all, how many types of front seat were fitted to the HC? on my '77 estate I have a raised box section welded to the floorpan on the sill side where the seat runner mounts and the base stays put but the back tilts forward. On the project car (no seats with the car) there is no welded box section so I assumed they were the tilt type where the base tilts forward via a bracket bolted to the floor at the front of the seat. But there are no holes in the floorpan in that area. I have 2 holes parallel with the transmission tunnel and 2 holes parallel with the sill in the same area as the '77 car. Am I missing something? (a mounting frame for early seats?) Any pics or info please. Thanks
Marcus
