'64 driveline rear gear ??
Been lurking for awhile on here , been into Chevy trucks for bout 35 + yrs . Currently own. '37 Chevy pickup , street rod . '70 short step '82 long fleet . An bought a '64 long fleet about 15-18 years ago an been in dry storage till now . Time to get it done . Have question on running gear , currently 292 3 speed . Have '83 spindles an brake parts for disc up front . '76 power steering box linkage . Have a '85 rear with 2:73 gear set . I can mount '85 rear into. '64 easy enough , question is how would 2:73 gears be with the 3 speed manual trans. Won't be pulling or husk long any loads . Was thinking first gear may be a lil slow going . Your thought ?

Re: '64 driveline rear gear ??
You probably have 3.08 so it won't do any good anyway.
Second thought is find out what you do have and upgrade the stock 12 bolt, a much better rear anyway.

Re: '64 driveline rear gear ??
The stock '64 rear is 3:73. The '85 rear is 2:73. Planned on putting the '85 rear under the '64. Was just wondering how the 2:73 would be with stock 6clynder and 3 speed trans .

Re: '64 driveline rear gear ??
In my opinion, 2.73's are way to high of a gear for a 6cyl, 3 speed in a truck. That is unless you are running really really short tires. I would recommend changing the gears in your 12 bolt to 3.42's. Some guys have gone with 3.07's, but I think that is a little high of a gear for your combo. Your tire size also plays a role in gear selection.
