More cab swap questions

[Farmstore34]

I've been tearing down the cab on my 72 K20 and have found it surprisingly straightforward. I am planning to swap it out for a nice 67 cab I found, but I would like to double check a few things, and hopefully learn from someone who has done this.
#1. Can I pull the cab off and leave the fenders in place? It looks like it to me.
#2. Is the electrical system the same between the two? The 72 had 1 connector on the instrument panel (which was really cool). I know the fuse panel is in a different spot on the 67 but I'm hoping the connector going to it is the same as the 72. I do not have the 67 cab here yet to compare.
#3. Where have you'all bought the new cab mounts? I doubt this would be a NAPA item.
Thank-you all in advance for all of your advice, past and present.
Colby.

Q1 - I guess it is possible, but I think you have a great chance at the cab hanging up on them. It's awkward enough pulling one without worrying about your fenders.

Q2 - wiring is different. For one the way it mounts in the cab is a little different, as well as the interior wiring is a little different for the placement of the switches. Also, if you weren't aware the emergency brake rounting and throttle (cable vs rod) are different.

q3 - I got My cab mounts from GMC Pauls or Tim Christian (I forget which one at the moment)

so will the existing 72 harness plug into the 67s fuse panel thru the firewall or am I going to have to completely rewire the interior? This cab is nice but not worth a headache like that. I sure wish I could find a good 72 cab!
