Ive been collecting parts for a dr who from scratch. No donor.... For nearly 2 years, im close to having everything. It's going to come out to about 7k i think when done. I believe it would cost more for MB but it'll take a long time to collect the parts, you just do it slow over time and when you see an ad with a part you need dont wait and pay the premium if ya have to. I blew it on a set of NoS plastics thinking more would come out (they dont). Ive almost given up several times but havent just yet. Best of luck
