Tom,does it have a dizzy?If so,it should be the Hall type ..Can be used to trigger any efi system..Is it mpunted on the rear of the head?If so,blank it off and put into the std position..It might need a bit of coaxing,I dont know,have never worked on a rear dizzy engine

But anything is possible..
On the old 12v you would not need the 4mm spacer for the flywheel.,only new generation engines..
Gtv sump,gtv oil pump,eng mounts,bellhousing and flywheel-
You should be driving after all this..
