01 cab upgrades

[MT2thDOC]

My 01 cab is my DD. Looking to make some upgrades and would like some advice from those who have "been there, done that". Body has a few VERY minor spots, but the interior was rosewood and has severe cracks. As far as the body, looking at the "Fiberwerks" kits and replace/upgrade interior (new stereo, etc). As to the engine (38K miles)...anything "street legal" is open! New engine or multiple upgrades? Suspension and brake upgrades as well. I plan on doing this just for "fun" and plan on keeping the car for a long time. For the "purists" I have a pristine 1985 930, all original and will NEVER get a mod. Very much appreciate all input!
