You may be able to cut the floor post off of the Autopower and replace the bases with boxes that spread the load up to the sills.

50# is worth about 1sec at Sebring in my B car. 100# is 1.5 at 2:45. The fastest cars will be 5# over on the scales post race, IMHO. I am

That's a longer track than where I go, but 30# should be worth a few thenths anyway. If I lose 50# I can run more fuel, so the weight distribution is better.

And, unless something has changed in the latest GCR, IT tubing size is determined by min. weight MINUS 180 lbs.....

9.4.1.F.4. For purposes of determining tubing sizes, the vehicle weight is
as raced without fuel and driver. The minus tolerance for wall
thickness should not be less than .010” below the nominal
thickness. Improved Touring roll cage tubing size are to be
calculated based on the published vehicle weight minus 180
lbs.

That makes mine a 2100 lb. car. 1.500 x 0.095 should work.

I didn't know NASA got up our way! Some day I may check that out. Do they have a place for an ITB car to play?
