if its got the comet 108 u can use a YELLOW spring.worked realy good in my 85 vmax w/ stock waits or add 2 washers to the spring 
. 
. i just have the stock clutch.. someone said the try green/yellow spring.. but they never said how high it raised ther engagement.. i was just gunna buy a spring thats the same size but has a higher pretension. possible a purple.
