I didnt remove the big can when i changed those inside. I loosened the bolts, snipped the wires to separate the big can from base, unsoldered a lead or 2 from the resistors to get the base to lift up an inch or more and began to work both sides of the pins with a pencil iron and a LONG pair of needlenose pliers to manipulate the old wires out, then to add the new caps in.. Since my speaker wires were frayed, i clipped em out since the speaker was on a trip to soundremedy anyways. I later went with a 4 wire cable and tucked the caps in as seen in the pic i posted.. But yeah, that surgery was quite a pain in that corner..
Cant wait to see that corner after your upgrade...
