Plunger depressor rod/spring problem - Arms Republic Slide Parts Kit

I actually ordered a Ranier Arms Glock 19 slide kit (from Dvor, Optics Planet's discount site), but in the the Ranier Arms box was a ziplock bag labeled "Arms Republic Glock 17". Given that Glock 17 and 19 slide parts are all interchangeable except for the guide rod, I decided to give it a try anyway. I managed to get the extractor, firing pin firing pin safety, and channel liner all installed, but ran into problems with the plunger depressor rod. Maybe I am just an idiot, but I could not get the spring to attach to the rod for the life of me. I think it must be out of spec, but if I run into the same issue with the OEM parts I just ordered, I will update this review.
