What's the ratio of the D300? Is it significantly more than the NP231? I know it's gear driven, not chain, but that's not the only reason to change it out. (vs. SYE, HD output & etc?)
Which is gonna cost more, retubing the HPD44 or flipping the 300? Are you breaking the front 44 now, to warrant the 60 upgrade? You know how much 60s are right (at least out here)?
I've spent the better part of this year (and the better part of $6k) building my Junk, and am debating pulling it apart to build it again with different axles & front suspension layout. Sucks cause I dont want to miss out on more wheeling but I'd like to be more confidence in my rig. So I know where you're coming from.
I'm also maybe considering a pass. side drop but there's so much in the way over there, starter, floor panel, exhaust. It's alot more work to do.
