Repairing a 28 year old bike given to me in pretty good condition. I've been working on it a lot hoping to ride/commute. These pedals are old, some bits broken and I want to replace them.

I've tried everything I can think of. I am pulling/pushing to the rear of the bike with all my weight. I have used PB Blaster. I've put a heat gun on it for at least 5 minutes. It just won't budge.

Any ideas?
