[Healeys] rear oil seal conversion

[Oudesluys]

To smooth out the vibrations of 3 bangs per revolution on 6-cyl engines. 
If you fit an overly light flywheel you may cause severe damage to the 
gears and some bearings in the transmission as these pulses/vibrations 
can cause very high strains.
How far you can go I do not know but although some lightening of the 
flywheel of the AH is certainly possible and desirable (as they are very 
heavy) I would think more than twice about an aluminium flywheel.
