Hello all, I'm pondering doing a gearbox upgrade as I have everything out of the car for my restomod and my 5-speed gearbox is "missing" 5th gear. The car is a 73 240z Europe edition and I believe I have the FS5C71B gearbox mounted in the car. Searching around I found recommendations of the FS5W71C swap from the 180SX, 200SX, and 240SX. I can find plenty of rather low mileage FS5W71C gearboxes for sale so that is not a problem. I read the following guide http://zhome.com/ZCMnL/tech/240SX5spd/transmission.htm and it is highlighted that you need the FS5W71B bell housing. Questio
