Engine block capacitor

Engine block capacitor located by the oil filter seems to have the purpose of eliminating static from the radio but also affects the oil presure gauge. Looking for a replacement I see only those intended for pre 1984/5 models. Are they the same and would they work.

Got the replacement today. Smaller with tiny hole for the mounting bolt, shorter pigtail but I can make it work. Marked either 15 or 1.5 micro farad, can't make it out. Original is unmarked or the stenciled value has faded. Car runs the same with it either in or out.



Making progress on reassembly. Sanded off rust and repaint.

I want to add boxes to my SA but we have that region blocked. I'm sure that entire area is removable or is it welded in ?

Easy remove. Lot's of different screws, bag and mark. Lower screws next to doors may be rusted. Penetrating oil helps. Be careful, I despite being careful twisted one off, center top.
