It looks ok if the replacement capacitor is of correct voltage rating etc

Hi inecik38. I'm interested to know what the two wires that appear on the top of the cap are for, or are they wires? I have re-stuffed the twist on caps by epoxying one of the base disks and mounting ring to a 1/8" (I'm American which you might have guessed) ring of 1" pvc pipe, two terminals are bolts through base with terminal lugs both sides, then slip it back up into can and small screws through side of can and into pvc ring. Ground is achieved by soldering narrow strip of sheet metal to mounting ring then up side of pvc ring to neg of caps so when can pushed over it a strip pressed between can and pvc ring. No wires out top. Twist mounting will ground to chassis. From your pics can not determine polarity of wired caps. If neg to neg and pos to each of the two terminal strips out of bottom should be fine. How do you get gnd (negs) to chassis? PL

Dear PLG ,there are four wires ,2( +) and 2( -) but there are no two wires in my picture.
