yup, there is a trader on here somewhere who sells them. just work your way back copper plugs, correct head and gap coil packs (there just old and should be replaced if not done so far) coilpack loom, as stated.... cooked. ignitor, also just old just do the basics man, as you will have the sparkplugs out, do a simple compression test,
pull off rubber (usually crispy by now) vac hoses and check for cracks leaks,
check your fuel filter ect so many threds on this kinda stuff.. i know your mechanic has checked them but really man there is only so much you can just check without replacing anyway.
