Hey all ...

Thinking about purchasing the '62 that '66burban' has for sale...

If it happens (sweet talking wifee

) would like to convert the rear suspension over to trailing arm....and I have a spare clean '63 3/4 ton rolling chassis for parts.

Will the trailing arm crossmember from the '63 interchange into the X-frame ??

Wondering if swaping the frames would be a better idea ??

I could correct the wheelbase, and graft on the rear frame horns for bumper mounting ??

Yes, I am going to get the '63 BBW going first.....

Thanks guys ...

If it were mine, I would shorten the '63 C20 chassis and use that if you can. For me the '63 and up chassis' are much easier to upgrade to my liking. Yes I know I am always talking about keeping your original frame, but this is an instance where it is not difficult to do, and is a worthwhile upgrade. Of course keep in mind the DMV issues.

Dont think you will have a problem adding the trailing arm xmember to 66....

So....swapping in the xmember is not as easy as 1 2 3 ?

I wouldnt mind swapping frames ... Not a big deal, really.

I dont think the CA DMV will mind either....

**Captainfab** · 05-16-2012, 01:23 AM

I'm really not sure just how easy it would be. I would have to look at the '62 GMC frame I have at the shop to get an idea. I guess I'm just a little biased as I don't care for the '60-'62 X-member frames.

**ChiefRocka** · 05-16-2012, 01:32 AM

Either am I.

I had that 62 for a while, and wasnt impressed.

'63 and up, for sure

Sorry I didn't catch that it was a GMC ..... Leafs ????

Yeap ..... Thats why I was asking about converting to trailing arms.

I dont mind leafs in my trailer or Stupid Duty that'll haul anything I throw at it .... But in this I would want coils .....

Was 62 the first year for leafs? Both my 60 GMC truck and my 60 GMC suburban had/have trailing arms.

I believe the '63-'72 GMC's had leaf springs as standard equipment, Trailing arms and coils were an option.

John, I'll see if I can remember to take a pic of the '62 GMC frame I have so you can see how the trailing arms mount.

**Captainfab** · 05-18-2012, 12:01 AM

Here's a few pics for you John.

**ChiefRocka** · 05-18-2012, 12:54 AM

Thanks for the pics !

That center section closely matches that of GM fullsize.....ie Impala frame.

Billy (66 burban) called me today and informed me that the rear is in fact coil sprung.

So, I can run that for a while...but still like the idea of the frame swap.

John
