L65 crossover recap advice

Hello, new to the forum here and in need of some advice. We have a pair of L65a's in beautiful condition. We have owned them for a couple months now and I am wondering about the condition of the capacitors. I know they are 25 or so years old. Should i just go ahead and replace them? and if so, what type of modern caps would you use?
Should I only replace C1 & C2 as shown here, and keep the exact same values? or are there other components that may need attention?

this is my first post but i have been following/catching up on the 4345 DIY with great interest. I was about 12 when my big bro walked me into a pro audio store where the guys there were playing around with a set of these. Ive been wanting that sound ever since.

Thanks in advance to any and all
