The cab and front sheetmetal are the same from 1/2 ton to 1 ton but the boxes are different lengths. So yes, the 3600 front clip will fit your 3100 cab. As for the price, that's all up to you. I've bought complete running trucks for less but good, straight and chrome 54 grills command good money now days. In my opinion, if it's as nice as you say, it should be worth that,
