New with a question

[ColinPierce]

Hey Gang,

I was informed about this group last week when I was picking up some parts for my 69 build from a member. As of right now I have a 69 cab and frame and another 72 frame.

While looking at the two frames I noticed on the 69 the rear cab mount brackets are only welded on the frame while the 72 frame rear cab mounts are spot welded and riveted on the frame. Is it normal that on some years the mounts are just welded to the frame?

Moving this to the 67-72 area so your question does not get overlooked. Welcome to the site.

From what I recall, GM riveted everything on the frames together that wasn't expected to ever be removed, like all cross braces, cab and bed brackets, etc... From what you describe, it sounds like the 69 frame might be a cut down longbed frame and they relocated the cab mounts. Is there any evidence of the frame being cut down?

[ColinPierce]

I will have to look closer. It didn't appear to have been cut when I looked it over to buy. Then again I was told it was an original swb frame. I'm just trying to decide which frame to use on this build. I have a long ways to go in collecting parts still

This is one that Was cut down and here is what to look for. the last pic shows were the bed mount is taken from at left & right of that chain. There should be two sets of holes on left & right side top of frame not being used just about 12" in front of the RIVETED original bed mount.

Ok I will check for that. I'm about to pull the cab off here in about a week or two once I get a metal work quote

I re read your original post and what you ask for about the Cab mounts I have no idea in where they would be relocated to. I thought seeing a frame cut down you would kind of see where to look for any signs of splicing or added on gussets in on the frame. Some kind of reinforcing would be visible.

[ColinPierce]

Today I was able to get the steering column out and pick the cab up from the side and tilt it. Looks like I have a poorly cut and shortened frame. Still not sure why the rear cab mounts are not rivited because the splice is dead center under the cab. And looks like it was cut straight top to bottom and a small patch plate. Because I was by myself I couldn't pick the cab up and move it off the Frame but just tilt forward. I will try to take some pictures but I don't think I can add them on the forum.

As long as they are small enough I think like 480x480 or something like that.

When I try and post it asks for link

A couple of things to consider. When lifting cab, keep in mind they are heavy on the firewall side and can tilt over frontwards in a hurry. (Ask me how I know). And when mixing year models with different model frames, there is a difference with the radiator core mounts. The 67 and 68 uses one style of mount and 69 thru 72 another. And the frames have slighty different core mount holes on them. There is a formula for which mounts to use but it excapes me at the moment. Good luck and welcome. This website is invaluable for the info and help.

[ColinPierce]

Thank you for the welcome.

Have a few more questions. on the title gvw is 3700. Am I right to assume this would be a SWB? Checked the frame and the partial VIN matches the VIN on the door jam. Now the partial vin was not under the cab. Good news is the Cab and front half of the frame match the Title.

[seafoam68]

Just looked at my 68 swb fleet. My dad bought it new so I know it is not modified. The gvw is 5000. Also re read your post. Since you have a 69 cab and 72 frame you should be ok as far as core support. Just be sure to get mounts for those tears. The cab tilting over still applies however. Lol

[ColinPierce]

Ok. Title shows 3700 on this one. Yeah cab I was actually suprised how easily I picked it up. Guess all those years in the gym payed off lol. I knew I should have just waited and tried to find a complete truck.

[haysonj]

I have both a short and long 69 frame and the cab mounts are riveted only the factory did not weld anything on these frames so your cab mounts were moved for some reason

I don't have to ask you how you know about the cab tilting forward. I ALSO KNOW ,(ask me how I know). LOL LOL

Try This Mr. ColinPierce. Posting Pictures

will this work the same using a mobile device?

I don't know, I don't use my smart phone for posting I only use a Computer. My Smart Phones only have a 2 1/2" x 4 1/2" screen so why would I use it when my Computer screen is 22". Your on your own there.

[ColinPierce]

You have a good point. I'll upload my pictures to my laptop tonight. Basically I'm at the point where I wanna see if it's worth anything to someone else to fix. I have another true swb frame I will use.

Keep us or me posted on if it worked for you or not. Plenty here that can help.

Back to the cab removal thing again, i borrowed an idea i found on here that worked well. I made a 2x6 box about 6 foot long and 18 inches wide. Cut notches in side rails for door frame to fit into to keep it from sliding. In one of the 2x6's running flat along the bottom, holesaw a 2-1/4" hole. Obtain a hitch receiver with a 2" ball on it. This will slide into the end of a cherry picker. Put the ball thru the hole in 2x6 and lift cab with cherry picker (run under truck from side) when you get a little clearence, roll chassis out from under it. Keep in mind placing it offset towards the front of cab to account for counter weight of cab. You might find the original post on here. I will try to post some pics later as well.

Is this what you have in mind

[ColinPierce]

that's a really cool idea

[Grumpy old man]

I pull cabs and beds using a couple 2x6's and my engine lift by myself almost weekly it seems some times , just remember not to get anywhere close to being squashed when lifting these things , lifts fail , boards slip ,straps break .....
