Hello have an RPM FNR box. Was the beefed up later model. Input shaft is splined to suit Suzuki sprockets, Brand new never installed or used. Ratio was to suit a busa and some 31-33 inch wheels. 930 cv flanges.
Decided to go a different direction. Located Mt Barker SA but can ship. Email chris@happychomper.com.au
Was 2500 us plus shipping plus customs etc was about 3200 Aus by the time I got it here. Yours for $2000.
