Project low and slow as my son calls it. 1949 Chevy 3600 that was last registered in 1974. Been in my family since almost new as far as I can piece the stories together. Been sitting in the barn for 30 years, but it was driven into it when they parked it. Being a 3/4 ton is the biggest challenge, mainly with the lack of availability of taller rear gearing. 4.56 gearing will not work for me. I would like to cruise at 60-70 on the highways. So changing the rear and is a must. I do have access to a 61 GMC 1000 parts truck. Does anybody know if that rearend is the same track width as my stocker? I have no idea what the gearing in it is. Not even sure what was available that year. What other common vehicle rear ends would I use? The front I am looking a donor 1/2 ton axle and brake set up to take care of the front change over. Eventually I will lower it and install a brake upgrade and power steering. Any advice from someone who has done this transformation?
