Alternative Points backplate for CB72/77 ?

[Phil-UK]

Anyone know if the points plate from a CB350 ( say ) will fit on the CBs ?
Looking for a later set that have 90 degree apart points but with the ablitity to
adjust both points idependantly without altering the gaps.

When my triumph had points the Lucas 6CA points had an extre adjustement plate under
1 set so you could get the gap ( dwell ) correct and then adjust the backplate to get 1 cylinder's
timing spot on and adjust the other by moving the extra backplate.

thanks

Phil
