V8 90 LT85 Gearbox noise

Hi all, My 90 with its 3.5V8 and LT85 box runs like a dream only having done 70 000kms or 44 000 miles, The only thing that concerns me is the growl when I let the clutch out when in reverse gear. Is that normal or should I be worried ? There is also a little take-up noise when changing up or down at speed on the open road. is this normal ? other than that she's a honey.
