It appears that GM used two lighters in the 60's & 70's. GM used both Casco and Rochester lighters during 1964-83. The Casco Lighters has movable parts and when pushed into the housing, the element goes through a sleeve. The Rochester lighter has no movable parts. Both lighters pop out when heated. Which would be correct for 1970 GS 455? Or does it depend on plant?
Bill, Do you have any of the components yet? 90* orange on the HOT and a BLK female spade on the ground? Do you have the knob yet?
