85 Diet advice

[softballnrd27]

Ok so I know there are few threads on here in regards to making our trucks lighter but I am wanting to make it as light as possible but not a gutted out "race" truck. Leaf springs are staying w/CalTracs Here are my plans(also looking for advice/suggestions)
5.3 swap done
Overload spring removed from each spring pack( done)
Pin-on Hood
battery relocated(done)
Possibly Scott's bolt-in IFS
Alum wheels(15x6/15x12)
Removing any non-essential x-members/brackets/shields underneath
Fuel cell between rear frame rails
Inner fenders possibly removed
A/C Heating unit gone already
Fiberglass front bumper?
Racing Bucket for Race day?

Things that might add weight:
4l80e(th350 currently)
9" rear(alum center section/disk brakes)
Roll cage
Eventually a turbo

What else can I do to get it under 3800lbs? Is 3500 out of the question? Should I try and remove any weight from the rear?
