I have a 72 short bed 6 cylinder manual 3 speed that I am converting to a 350/TH350 automatic. My problem is determining the axel ratio that I currently have. I have been told that all I have to do is raise the wheels off the ground and turn the drive shaft x amount of times until the wheel has made one complete revolution. Trouble is that when I do that the drive shaft only has to turn about 1.8 times to get the wheel to make one complete revolution. I'm sure I don't have 1:80 gears so I'm wondering what I am doing wrong. Any help would be appreciated. Jimx( ________ og kush pictures ________ macintosh games
Jim, The only way to know for sure what ratio you have is to pull the rear cover. On the ring gear are a series of #'s. You're looking for the ones in the middle of the group, they will be one or two digits then a space and then two more. Examples; 10 41, 11 41, 9 41, 14 43,...etc. To find your ratio divide the first # into the second. 11 and 41 is 3.73, 10 and 41 is 4.10 and so on. Yes, there are #'s stamped on the housing, but you don't know if the gears are original or not. Like I said the only way is to count the teeth yourself and divide the pinion into the ring, or use the #'s on the ring gear. Good luck, Brant
I was trying to avoid having to pull the cover but i will probably have to. I did find some numbers on the right axel housing facing towards the front but i can't find my notes right now. I am almost certain the gears are original because the truck only has 43,000 original miles on it. If I told you the numbers would you be able to tell me what they mean?

Tech 1, This is the code I found on the front side of the right axel housing: NF3896838. Hope this helps. Thanks, Jim ________ marijuana vaporizers ________ Rehab Help
that code did not com back try looking on the bottom sid e of the left or right axel tube to find the numbers. it say that the first three are letters that tell you the ratio and then four numbers to tell the build date and the last letter to tell where it was built.and it looks like it will start with a R
Tech 1 I did see a bunch of numbers on the back leftside of the diffirential housing but they just looked like 123 456 7890 But I'll try again. Thanks Jim ________ iolite vaporizer ________ star craft replays
Hello, Jim, tech 1 is your man for this one. He has more resourses than I have. After all he's one of my resourses. Good luck Jim. Brant p.s. It might be quicker to pull the cover and do the nasty.

On the front side of the differential housing are large letters "GM60". On the upper left back side of the housing I found the letters "CON" and under that 12345 67890 Does this help?

Charles F Rising JR: is there a tag that is bolted to the rearend cover? if so than this will have the ratio on it as well if not the time to do the nasty and pull the cove. Besides it might be a great time to replace the old gear lube .
I thanks everybody for all the help but I finally decided to pull the cover. Turns out I have 3:73's Thanks again, Jim ________ Honda SCV100
