Too long.Heath, if you want leg room, chop up a burb!

What I meant is when he is stretching the blazer he only cuts the body.@imiceman44
just to make sure I have this right...
The answer to chop a burb is that it is too long and would need to be chopped???![]()
You would need to add length to a Blazer in both the body and frame vs removing material from the body and frame on a Suburban. On a quick comparison I would expect less work and complications from the burb option but reality is neither options are straight forward.What I meant is when he is stretching the blazer he only cuts the body.
With the suburban he has chop both, and not the easy way cutting the overhang like most do with a suburban but cut the wheelbase down
The option was to use his frame from the short bed and stretch the blazer bodyYou would need to add length to a Blazer in both the body and frame vs removing material from the body and frame on a Suburban.

Thanks for your input Stephen, some good info I'll keep in mind.I've done a lot of this, here's my thoughts:
The half cab is a nicer vehicle for everyday use for sure. Doors seal up better, whole thing is quieter, top seals well, etc. Lot of mentions of these benefits and more. None of this applies to what you want to do as you've brought up. For a fun truck, the full vert is good.
My half cab weighed about 75 lbs when I cut it off my '82. And it is on the top of the truck so it's a good place to lose weight.
The drop floor in the later K5s is nice to have. For kids, maybe not so much since their legs don't hang down very far but it's still nice.
Start with the K5 frame and graft the front of your K10 frame to it. Trying to use the truck frame isn't worth it. Splice the two so that you retain the belly section of the K5 along with the fuel tank mounting, etc.
Stretching the whole thing is a great idea. Check out all the stretched broncos from the desert pre-runner world for some ideas there. Getting wheelbase to 115-ish or a little more does nothing but help. Starting with a 'burb frame would be good if you do this. Their drop center is longer to accommodate the longer passenger area and it could easily be cut down to whatever length you need. Or maybe you just build the belly section out of some rectangular tube and splice that into a K5 frame. That way you get straight rails and some extra beef in that area.
Give up on keeping the shocks under the bed floor. For what you want the truck to be, the suspension needs to come inside and build seating around it. It's very possible to have a 3 wide bench with the shock behind it, especially if you stretch it. And staggering seats like you mentioned gives you even more options. I have this now and it's the same layout I had in a full body at one point. For something whose purpose in life is to be fun, you should have at least 16" of rear wheel travel and if you stretch it, the door is open for more. This is a lot different from 12".
Don't splice an early windshield frame. The soft tops attach nicely to a cut down later frame. The only reason to put on an early frame is to use an early hard top which is not in your plan.

Pretty much.Tempting but I imagine shipping them to Alabama would be miserable.
He figures it's easier than trying to figure out a detail of how to finish it.Why do you need a '73-'75 windshield frame if you are not going to use a factory top?
