I need to find a cheap replacement for my 03 Civic EX Manual Transmission and clutch so I was wondering if anyone knew if I could use older D type engine transmissions and/or clutches? The clutch was going to be around 250 and the transmission around 7-800 but I know I can find an older d type trans for less. Would any fit? If so, which ones or are they all fairly interchangable? Short of that, does anyone know where I can find a cheap 03 transmission?
