I have removed my 1951 chevy 3/4 ton pumpkin and a 1968 20 series pumpkin and a 1969 30 series pumpkin they look to all be the same 32 tooth ring gear and 7 tooth pinon gear. there are numbers on the 1951 (3882103 GM 7-32 1 51) and on the 1966 (3768612 GM 7-32 8 1966 2) does the 7-32 mean 4.57 ratio

Anybody know the weight of the pumpkin ? I found it was a challenging thing to pick up and carry out to my car! | | |

3652510 GM 9-37 2 52.
37%9=4.11
Feb '52, I assume.

Truckernix,
My wife shook her head as she saw me walking out towards my shop with our bathroom scale. With my son's help we got 100-101 pounds.

Actually the only tricky part for me was picking it up and putting it down. The carrying part was OK. The junkyard guy was at least my age and he handled it like it was nothing. | | |

(like the spare I have sitting on my garage floor)
There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

Be yourself. If you are ever lost, It will be much easier to find yourself if you know who you are!

I know were a posi unit is out of a 70 3/4 ton van (dont know ratio yet) are thay worth vary much? | | |

You might want to look at "Randy's Ring and Pinion" website. There might be some answers there. I found it very educational. | | |

Lockers (posi) are usually worth more, especially in 1/2 tons. But to put one in an AD truck, you need to swap the differential, not just the pumpkin.
