700R4 to D300 mating...

[sled_dog]

As far as I know the 300 has the same bolt pattern as a 208 or 241 so adapters shouldn't be an issue, but they have 23 spline inputs vs the 27 spline. So what are the options? Anyone make new input gears for the 300? I'm sure someone could get 23 spline output for the 700R4 but transfer case gear change would be a nicer option. This is for a Jeeper friend, hes weighing going with a 700R4-205 or 700R4-300 combos. I am pushing towards the 300, I just like the cases, the gearing options and upgrades for them make them decent cases I think.

THanks but not a big help. It says:

Transmission disassembly is not required if you have the right TH700R4 (see, Compatibility). Our #8681812 4wd output shaft is available if necessary.

But doesn't tell you what the "right" output shaft is. THe only output shaft I know of factory for the 700R4 is the 27 spline 4x4 and the 2wd output shaft. Neither will work for a D300. When you go to the link to check compatibility, it says you have to change output shafts.

Well , reread it again , verbatim , and click on the linky there .

[font=Verdana, Arial, Helvetica, sans-serif]" Our #8681812 4wd output shaft is available if necessary. "
This is the 4x4 output shaft for TWO WHEEL DRIVE 700r4's
That what you convert , 2WD TRANNY TO 4WD TRANNY SHAFT .
If you have a 4x4 700 ignore this .

[/font][font=Verdana, Arial, Helvetica, sans-serif]According to this kit # 137 , it comes with the new input for the d300 , so you only have to use a 27 spline four wheel drive 700r4

[sled_dog]

they won't sell just the input, well he said he would but he'd charge me $409, ha.

Advance makes on too , but couldn't find a part number for it separate from their kit . But its funny they sell a 29 spline , and the stock d300 seperately .
