[Oletrucks] Two basic questions

follow this link and scroll way down for lots of rearend info

looks like the 47-55.1 rearend is 60'' wide only 2'' narrower than the
55.2-59 trucks at 62''

i run a gen3 trans am rearend that is 61.5'' in my 58 w/ 3.27 gear, disc
brakes and posi
however... because i am lowered with the mustII, rear axle flipped on top
of the springs with wider wheels and tires
i have a hard time getting my rear tires off. it requires jacking the frame
not the axle
and wiggling the tire out from in between the hub and fender, not pretty
but no damage yet :)

if your rear axle is 60'' wide i recommend going with a 58'' max width axle
just to avoid my problem
if you plan on lowering your truck, since you have the mustII i figure it's
lower than stock
if you want high mpg then go with a a 3.25 to 3.50 ratio, lower than 3.00
you may loose the power band

as for your trans, definitely go with the 700r4, though the 200r4 is just
as good
with the 700r4, 3.27 ratio and 350 sbc i get 20 mpg on the highway
i do have the gm ramjet 350 (350hp and 400 ftlb) so my power band is a
little better than most sbc
i can still burn the tires thru 3 gears if i want to
