Gmt900 cab mount swap

[Red jack]

I have a 90 rclb and I need cab mounts and I've read Gmt900 cab mounts swap on ex cabs could I swap it on a regular cab or is the mount to big, if not what is a better than stock mount for a daily driver?

Physical you can do it. Ive read that 900 mounts on a reg cab rides really rough.

I want to have a smoother ride quality I installed Monroe shocks last year and that helped but it could be better. Thanks for the info tho
