I have a 89 325iSport and am going to do the M50 NV swap in it. Having the 325IS already I figured I could reuse some of the parts on the car, I want to use the 260 gearbox, but I've heard it will sit about 10 degrees off. So I was wondering if anyone knows where I can buy a already modded crossmember to fit the 260 gearbox? and also since I already have a 3.73 LSD, will it be any good with the M50?
Any input would help, and thanks to all. 
Have seen them on Ebay, But also heard of people modifying their original mount.
You also need to modify the shifter for the tilt or else it hits the tunnel.
And yes if you find the ratios fine with the m20 (IMO 3.73 with e30 gearboxes is the best ratio) then it will be the exact same with the m50. Though power band different..
