Hi Folks,
Just my 2 cents – I thought that all Arrow cars had the fine spline Clutch and only the Holbay powered cars had the larger clutch fitted – if the clutch is the 7 1/2 fine spline I believe those discs are still available and only the coarse spline discs have dried up.
I also assume that the suggestion to move to the larger clutch refers only to the later Holbay set up because I do not believe that the Arrow cars, with the longer bell housing, can accommodate the earlier “series” Alpine 8 inch clutch because you also have to change the release fork and pedestal to change even a SV Alpine to the larger, early clutch set up.
