Yeah only overdrive with the 6spd, BMW folk are an odd bunch. It can work with some setups, but definitely not compatible with everything. Will make the car scream, though. 5spd ZF paired with 3.69 would be manageable imo but not ideal for some people. ~70mph@3500RPM in 5th gear isn't the worst. With a 420g 6spd ~70mph@3000RPM, or ~65mph@3000RPM with 4.10 gears.
This is a situation where a Z diff would come in handy, as you can get them with longer ratios (3.357/3.538). I also believe there are some Nissan R200 diffs with 3.538 FD (some NA RB20/25 auto cars) which might not be as easy to find, but ya never know, might be able to get one for a decent price.
