hemi dart seat brackets

If you guys have come up with any measurments on the bracket and don't mind sharing your findings i would like to build a set myself. If you can lay a tape beside one and take pics from all angles i can build em. PM me if you have been successful. Thanks

I bought a set of these seats and they came with only one set of tracks. My swinger is a 72 original bench seat. I removed the bench tracks and they bolted up exactly in the same holes as the 68 Hemi's. The floor pans were of course different so I bolted on a 2" long x 5/16" threaded hex coupler (I think thats what they are called), on the back only and the seat looks awsume. I couldn't use the original floor pan bolt holes because they were too far forward. I drilled new holes 1 3/4" back from the originals and the seat sits perfect and level. Some may say its Micky Moused but it works on this particular application.
