Personally, I'd say go with the 4-speed. It's tried and true and I really don't think these new 5 and 6 speeds are as tough as the old three and 4 speeds. Give me a T-10 Borg or a M-21 Muncie over one of those any day. I do sympathize on the issue of the overdrive though, but with 3.54 gears you aren't really going to need it. Hope this helps!
