Cab Mount Question - 72 C10

[mgm60]

Cab mount bushings on my 72 C10 Cheyenne have seen better days so I want to replace them but worry about fixing one problem and creating 6 new ones. Gaps on my doors, fenders and bed are all really good and all trim lines up almost perfectly so I'm concerned about throwing alignment off with a new bushing kit. I've looked at some threads on the forum but don't see anything about trying to keep all this stuff straight and I know there several different kits available. Has anyone got a recommendation on a "best" kit and advice on how to avoid problems with alignment?
My biggest concern is since the old rubber grommets are compressed, when I put the new ones in my cab is going to sit higher than it does now.
I've included a picture of one of the cab mounts.

Thanks and Happy New Year!
