Original Bucket seats installation????

I don't have my cab here to confirm this, but it appears that the dimples refered to are visible in a couple of your pictures outboard of the seat brackets. Looks like 1/2"-3/4" out from the existing holes. This is consistent with where my original buckets were mounted from the factory.

You may be right. There are some dimples that look like spot welds. Any chance you have any pictures of your seats in relation to the console from an overhead view like looking through the back window or windshield? I would like to see what the gaps are between the seats and the console. thanks

These look like dimples in the picture here:

Those are the ones I was referring to. I don't have any pictures that would help, and the truck is currently disassembled and 2000 miles away. If you can wait about 3 weeks I can get pics. However, I estimate the seats are about 3/8"-1/2" away from the console. I have some shots with the seats installed but from a 45 degree angle... not much help.

Thanks for the offer, I appreciate all the info I get from guys on this board. I have never installed these so I kinda want it to be right. I already drilled the pass. side. But I'm pretty sure they are wrong. I can't wait 3 weeks but thanks anyway. I have seen some 45 and side shots and you really can't see the gaps or lack of. thanks

I found this old thread http://67-72chevytrucks.com/vboard/s...d.php?t=352079

Perhaps post 8 will help. I'm still searching for others.

Hi Mike, I have owned decent share of these trucks over the years and done a few 69-72 truck bench to bucket conversions in them years and have not came across any floor pans having the dimples already in place for drilling the bucket seat mounting bolt holes, maybe that was a regional/plant type of deal. 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.

You are welcome and I am always glad to help out, as far as using the whole bucket floor pan or just removing and then adding the OE bucket cross support and braces to the original bench seat floor pan, I have done it both ways and in the end prefer the second method. You did a good job on building your bucket brace setup, that under shot looks better than most of the bucket converted trucks running around these days. Now tell me this, just yesterday I took a closer look at five different 71/72 cabs and seen NO dimples for drilling the bucket seat mounting bolt holes, I have three factory bucket floor pans here on hand and know where the said missing dimples should be, I did see some spot weld marks present but no dimples pertaining to any sort of a drill pattern, did your floor pan have the above described dimples where you ended up drilling the other eleven holes?
