Hi guys thanks for the ad, i am rebuilding a 1970 mustang that came with no front end, engine or gearbox , im building a twin turbo 351w atm but have been acquiring various parts over the last 2 years, i bought a 4 speed manual box RF-D9BR-7008-AB over a year ago that was supposed to have been rebuilt but i pulled the top cover off it yesterday and surprise surprise its a mess in there, chipped gears and bits floating about lol , so i need to identify what box it is and find some info on how to rebuild it if anyone can help? Thanks again.
