I ran accross a few online articles detailing how to convert a dana20 to a gear ratio of 2.46:1 using dana18 parts and Bronco dana20 rear slider gear. (I just cant bring myself to pay $850 for the TerraLow 3.15:1 kit - nearly $1k for a dana20 after buying seals & bearings) Plus it would be more uniquie and a challenge to scrounge up the parts than buy some bolt-in kit.
The few articles all say to use the rear slider gear with the p/n stamp 18 8 58 on it. This gear is supposed to come out of a 66-72 T-style bronco dana20. Does anybody know if how spicer gear numbers work? I have been told by a bronco salvage company that spicer had identical gears with different numbers and any rear slider gear out of an early bronco dana20 would work.
Ive also had another salvage guy tell me that the third number referes to the production run. I know that this is incorrect since nearly all gears from a dana20 are 18 8 ##. Even if gears with different numbers may look identical (tooth & spline count) they may have different tooth pitch angles/etc.
Too bad dana doesnt publish info for their old axles & t-cases anywhere. There is too much wrong information out there about this info.
