You might check with: http://www.ring-pinion.com/home.shtml for more advice. Also at this site, they have a calculator you can use to determine RPM at various speeds with various ratios and tire sizes. | | | | | Joined: Aug 2003 Posts: 7 Member | | Member Joined: Aug 2003 Posts: 7 | thats great...thanx for that info | | | | | Joined: Aug 2003 Posts: 7 Member | | Member Joined: Aug 2003 Posts: 7 | but...will that rear end fit up to my ol 71 frame?or will i have to make some mods? | | | | | Joined: Feb 2001 Posts: 1,897 Member | | Member Joined: Feb 2001 Posts: 1,897 | The rear gear ratios were availble for your year of truck too. A buddy of mine put front and rear `71 C-10 running gear into his `63 suburban and only had to modify the panhard bar as he was lowering it.
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.
