67chev,
I
really like the trans. I don't think there's a better option for a vintage truck than this one. I think of modern trucks and S10s when I think of 5 speeds, and the 3 speed OD (or 4 speed) is really more nostalgic (to me).
This trans case is made of cast aluminum and probably weights less than the Saginaw 4 speed. I'm guessing the weight is around 80 lbs. Maybe less.
It's WELL worth the money.

It allows me to turn 2600 rpms at 80 mph in the fast lane on the interstate without having to change the stock rear end. Super sweet!

BTW my truck is a 1966 2wd, shortbed stepside.
