Has supra large spline:thumbsup:The box is not bad on manual shift, works really well with a PRO-Shift or similar fitted. Miles better than the old H-pattern Trust dog box. Bit noisy with the straight cut gears, but quietens in 'cruise' mode. Need Ron to clarify if its the standard input shaft or the oversize one. Better with oversize and change your clutch hub to suite.
I've got two of them. Back up from Tim at SVS is good too.
