G&J  let me start off by saying I really like your forum. 
can you please tell me where i might be able to find drawings on how to measure and build a tube chasis for a promod. i have asked at other sites 
and i get no reply or they tell me check out some ref. pages. whitch is sound advice but that only gets me so far. i have been building models on and off for 30 yrs but only stock . i'm ready to move in a new direction. I will deeply appreciate any advice..
