Anybody here have experience with 203 doublers?
For the 55 project I've been looking at adapter and doubler options between the NV4500(5.61 version) and the LC tcase, and it looks like an NP203 + AA adapter only adds about an inch more of drivetrain length than the straight through AA NV4500-Tcase adapter. NP203 option costs at least $200 more by my optimistic math, which would include a little work on the 203 to bolt it directly to the 4500. I plan to wind up on 60/62 series axles, 35" tires max. Maybe 4.56s, I like where that combination puts my final drive ratios on the street.
Do I need the extra gears out of the 203? Probably not...yet it seems a shame to use up all that space with a simple adapter shaft. In terms of gearing I could put in a 3:1 orion and probably be perfectly happy - I'd have twice the gearing spread that I do now with the 4 speed. If I use the doubler I'm probably gonna break something...
Other disadvantages? C'mon, somebody talk me out of this.
