I have pondered this too and have a similar situation. My car is woefully undervalued as appraised in '96 so I need to make some mods. My insurance is replacement value based on comparisons. Um, by their opinion...
I can see that going horribly wrong fast.
Since my car has not seen the road but once since 97 it slipped under the radar until I looked into it recently in anticipation. Now I am not happy.
I have seen ads on Speed for Grundy or Haggerty but Heacock is a new one to me.
