Bob that red truck is BEAUT!!!! I would just leave it alone and enjoy it for what it is already.... you know due to your 'advanced age' and all that kinda stuff....
(that you wrote about in past threads) 
I think you said you were 18 in '81!!!!! thats MY AGE!!!
and from all the advertising I see around all my local beach towns is
"OLD GUYS RULE" !!!!
I think you got a good recipe.... leave the truck for slow and steady.... and paint the VETTE up for some fast and furious times....
Good luck with whatever you decide!
