Re: FINALLY got Old Green after 20 years.

203 box to 205

1:1 = all high range
2:1 = 1 high / low
4:1 = both low

then magnum box is this combo .

1:1 = all high
2:1 = np205 in low
2.72:1 = magnum box in low
5.33:1 = both in low

sm 465 / 4.10 / 38" tires

203/205 low/low/1st = 105.43:1 crawl
magnum/205/1st = 143.39 crawl

reason i say magnum is if you have no range box stuff and need to buy it then its about a wash for 203 or magnum to a 205 .

plus i find the 2:1 or 4:1 o.k. but would LOVE that middle 2.72:1 at times .
