Original Bucket seats installation????
I'm trying to drill the holes in my cab for original bucket seats. I'm looking for some pictures of the braces and alignment of the seats. Anyone document their installation? I have the material to make the braces but would kinda like to see some originals.
Are the outside front holes used on LH and RH seat mounts? Thanks |

Re: Original Bucket seats installation????
Here are some pictures of what I'm looking at.
Notice that the seats are touching the center console on the sides with the bolts in the outer stock bench seat holes. ![]() ![]() ![]() ![]() |

Re: Original Bucket seats installation????
subscribed. Always thought they used the same holes as the bench seat - so, therefore, I have no clue.

Re: Original Bucket seats installation????
I have always thought that too but, it just doesn't look right. The driver side inside mount hits the tranny tunnel raised area before the bolt will fit in the hole too. I can force it in there but it's tight.

Re: Original Bucket seats installation????
if you look there are dimples in non bucket seat floors for bucket seat location. There are also dimples in the center floor pan for the console as well. The only direct bolt in is the the buddy bucket seats, all others must be drilled to fit.

Re: 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.

Any chance any of you experts have some pictures of your original buckets or a measurement from the seat bracket to the center edge of the radius? |

Re: Original Bucket seats installation????
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.

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. Jim |

Re: Original Bucket seats installation????
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.

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. |

Re: Original Bucket seats installation????
Okay, I bit the bullet and went with Mel's suggestion from the original bucket seat floor pan. Although I didn't build the brace that ties the two sides together I did make some braces from some old ball bearing drawer slides. They are the exact thickness and near the same width and depth. Here are the pictures of what I did in case someone else can use it. If you look at the pictures, you'll notice I moved the driver side hole pattern outward 3/4". this made the two seats the same distance from the edge of the seat to the door opening symetrical. It also made it where the driver side seat isn't bound up against the console.

Re: Original Bucket seats installation????
You really think it's necessary or just extra insurance? That rib that runs across the front is pretty stiff just by design. I would like to fab one up, I have already thrown a bunch of time at this though. I will look at it tonight.

Re: Original Bucket seats installation????
Hey Mike, judging by your pics, you are already well above and beyond the under side bracing found on most of the bucket converted truck cabs that I have seen. What about the question I had asked you in post #23? Mel

Re: Original Bucket seats installation????
I will add that the big middle brace can be found and removed from any early blazer, got mine from teeitup. Randy usually cuts them out when he parts out a blazer. If you get this piece you can use it as a template to drill the front holes in the correct location and then either use panel adhesive or weld it in. This piece really takes all the guess work out of where the holes should be.

Re: Original Bucket seats installation????
Hey Mike,
On mine, I used the outside front holes and then marked the locations with a Sharpie so I would have the locations exactly right with these seats. In the process of drilling I noticed the dimples that others have seen. Anyway, I went ahead and used the outside fronts as they would be more secure than what I rigged up, and the console just barely touches the seats at the front corners. Not snug at all. *shrug*
