take the upper hull of the M1A1, then take the ERTL star wars land speeder (i think). 6 tubes of milliput, 1 kingsize supaglue(CA), 1 bottle of vodka, use a blind fold when you pick youre paint colors, bodge them together, fill and sand then schlap on some paint!. finish the vodka first.
The vodka can double up for thinning acrylic paint!!!!!
PS let me know if you pull it off as all i need is the land speeder, j/k
