I didn't find fitting my new springs too much of a problem with them being weaker (thank god!) I simply compressed everything as you say and slotted a thin rod or screwdriver through the end pin hole which is easier to do when lining up with the inner holes. Once all is lined up tap in the proper end pin knocking out the thinner rod. I've found everything else easy to replace and fit if necessary which is another thing I like. Its a good gun to fix yourself, not that there's much to go wrong them. Such a simple but effective design. That original spring IS AWFUL. Way too strong. Ive heard so many comments about the difficulty in cocking. Until you replace it with the weaker spring can I suggest sliding the cocking hand upside down under the barrel so the thumb is pointing at the muzzle end. You get more leverage that way I think.
