I'll give this a shot to the best of my knowledge, when using the 69-72 truck bucket bracket setups and when going into an original bench seat truck cab, there is only one hole of the eight in the bench cab floor pan that's already in the correct place and that you are going to use when bolting the bucket mounts in. The one bolt hole (only one in correct location) that you should use is the RH fwd. most outer bolt hole, so it would be the pass. side fixed mounted bucket fwd. RH bolt, you will need to drill the other eleven mounting bolt holes. I have had these pictures of an OE option #A50 bucket seat floor pan that were taken for another member and then stuck away in a saved folder, not sure if they will help you dimensionally as they don't have any measurements but the pics do highlight all twelve of the bucket seat bracket mounting bolt holes and they also show how the factory used pan head filler screws to plug the other bench seat mounting bolt holes. The bottom view pictures highlight the factory added bucket seat cab only floor cross support & extra bracing. Hope this post and pics can get ya headed in the right direction, Mel.  |
Mel,
Thank you so much. This is exactly the information I was looking for. What you are saying is my pass. side holes I already drilled are in the right position. I only used the outer front hole and then marked the other three with it bolted down in that one hole. I'm assuming the driver side mount setup is wider becaus the outer holes need to go outward about 3/4-1" in your picture. Do you happen to know what the gap was at the center console between the seats on both sides? Also, when you installed these buckets on bench trucks did you fabricate that front brace that runs across the bottom of the rib at the front mounting position? thanks for the help.
