d20 doubler

[towpainter3]

Sorry if this is in the wrong place.
Does anyone have a kit or are there some ways to add a doubler to a d20 case I really prefer the do it yourself way but I'll do the kit thing if necessary. Im looking to get at least 5 to1 or 6 to1 and leaving my 4.56 gears in the diffs
or are there gears available to regear the existing case.

There aren't any real kits per say, but it has been done (called "cold duck"). D20s are just not the optimal front case.

If you have the length, you can do a d20 to divorced 205.
Put 3:1 in either case.

If you have a 727, your best bet would be to find an np203 off a dodge (get the 727 output too), and do a standard doubler to either a d300 or NP205.

This stuff seems really work intensive but if its the only way it will work. Thanks for the info and the links
