I'm doing ym bellows and shift cable on my '89 Alpha One. I can't get the old shift cable nut loose. I've been hitting it from both sides with MAPP gas and PB Blaster for a while and it won't budge. When I put the socket on it feels like it's gonna strip the head on the nut/fitting. Anyone have a trick to get these out if they're stuck real good? It's a pain because there's not much room to get any tools in there.
