MY87 yj now has 4.10's and the local dealer cant or doesnt know where to look for a speedo gear chart. Someone gave me a p/n 52067638 which turns out to be for a1990 YJ (38 tooth)
MY research shows i need 36 tooth. THATS not getting me anywhere cause the dealer claims he can only go back to 1990,
and the shaft on that gear is is to short when i looked at it.
Does anyone know what i need a p/n would be most helpfull.
87 YJ BA10/5 NP231-272 RATIO PUSHING 31"TIRES.

The part number tells you the tooth count......the last two numbers tell you how many teeth are on the gear. If you need a 36 tooth gear, then tell the guy that they part number you need is 52067636.

Here you go.....this article will help:
