Thanks for the post. I'm new to the forum and to Dodge trucks. I will be acquiring a 1967 D100. I don't know if it is a short or long bed. I know the 67 is 114"(short) and 128" (long bed) but I could not find any info on wheelbases newer than1980. I would like to put a newer suspension/frame under it. My question is , is there a later model frame that has the same wheelbase? If there is a website or you can point me in a direction any help would be greatly appreciated.
