Hello, I just purchased a used distributor...it has no vaccuum advance..and has an msd cap....i think its the 85551......Now the problem is...there is a white and a green wire comming out of the base of the distributor.............now....how do i hook this up..

I am going to buy a coil for it.tomarrow.... is it worth putting money into this ..seeing as though it has no vac advance..???? its like new.....................

Thanx guys...
