GREAT looking build!!!!
Had a couple of GMP 1/18 metal sprint car kits back in the '90's......one was a modern type with 2 side frames. wing or non wing piarts.
The other was a late '60's (?) style that IIRC had an Offy or Chevy engine options, as well as a spring front or torsion bar.....
Never built them....sold them somewhere around 2006/2007.....either thru Fred's site or Randy's site.....
