Seat question

I have a 76 1500 gmc that I want to put a current 40/20/40 split in it. Has any one tried this? Will it fit? I know I'm gonna need a extension bracket for the front feet of the jump seat and the inside front feet of the seats.

Thanks for any advice in the future on this topic.

Re: Seat question

You will probably have to shorten the outer brackets instead of lengthening the others. When I put 08 Silverado seats in my K5 the height was just right but k5s have flat floors not like a c10 pickup with raised seat area also my seats the brackets were all the same length all the way across I think the newer seats straddle the tunnel and don't mount on top of it

You wouldn't happen to have a write up or pictures for the seat swap would you? I want to put the same seats in my 89 K5 and was curious how it turned out. I checked the threads in your sig but didn't see it...

Sorry for butting in OP

Re: Seat question

No I don't have pics of it but all I ended up doing is on drivers side was make a frame out of 1in square tubing that was raise about 2in to the top and unbolted the factory mounts and bolted the sliders directly to the frame I made its pretty simple but passenger side was a little trickier cause I made it flip forward like stock I will try to get pics of my brackets

Re: Seat question

Took some pics today I used angle iron on my frame for sliders but square can be used as well for passenger side I had to cut original k5 front bracket down and put a piece of 10ga. sheet metal to allow it to bolt to seat frame not slider I didn't think I needed a slider on passenger side so I placed it as far back as I could the back bracket was unchanged other than putting a piece of 10ga. Across it. Both side panels still fit as well

Re: Seat question

Blazer floors are completely different than a truck floor and that wouldn't work the same.

Re: Seat question

Ok. I have 2009 Silverado with the split bench and it's the same height as the buckets my 76 has. I measured from where the seat tracks mount to the floor up to the top of the seat. The actual part that u sit on not the back rest. The buckets I have now had the inside legs extended with some 4x4 wood blocks.

Re: Seat question

I would have thought they would be to tall in a pickup but the 09 seats should be the same as my 08 so you shouldn't have to use the blocks of wood anymore. When I first put them in my truck three of the mounts bolted in and one was about an inch off but again it not pickup I did eventually make a new floor bracket just cause I needed something more sturdy as I wheel my truck hard so it's now bolted in with all 8 factory bolts

Re: Seat question

I'll take a few pics tomorrow. I think the wood block should come out and I'll fab up a bracket to mount it all to.
