Hello all.

I currently have a both an 8" and 9" rear from Mustangs.
Unfortunately, both have 3.00 open center sections. I would
obviously like to have 3.55 or 3.70(ideally w/ posi), but don't
know what these were originally installed in in vast quantities.

Besides a specialty vendor of rears and parts, what cars or trucks
should I begin searching under? What about options? Transmissions?
As a matter of course, will a station wagon or truck have a
lower/higher rear than a standard pass. car?

TIA for any all responses

look for manual transmission equipped cars though sales of cars equipped
like that reduced every year since the early 60's

For high gears in 8" check older Econoline vans and Mustangs II's

Again manual transmissions. remember these gear ratios were not often
something car buyers wanted (try finding a new car with these gears)

Many times older commerical vehicles do have the higher gears as
mentioned before. People ordering station wagons were not looking in
most cases for this option. Remember that many of the Ford commerical
applications came equipped with Dana rear ends

If your thinking of finding a third member in a yard I wish you luck.
There was a time were you could go and find 2-3 high ratios and posis a
day (along with 1-2 Lincoln disc rearends) but today (at least in Calif)
there are many guys who are beating the yards for parts like these. In
my area alone there are at least three that make their living at it.
