Newbie with a 69 CST/10 long bed

Just a general reply to all comments with more detail of truck.
307 with 3 on the tree. Factory A/C not working. No PS or PB. Would like to convert to compfortable daily driver with ps, pub and at. But part of me enjoys the originality of the old truck. I was going to immediately do a 2.5 spindle drop, but chose to make it roadworthy and do some homework. Front drums were shot. Rears were good so I did the front and master cylinder. Only cancer is in passenger footwell by the kick panel. Other than that it's an undamaged straight California truck that has never lived more than 30 miles from me. Engine has 25k and purrs like a kitten. Might be correct year for the truck though. I have original owners manual and original build sheet.
Not original trim or side makers?
I was wondering about the mirrors. Want to replace but couldn't find the same shape from LMC or elsewhere so was scratching my head. Looks all stock under hood. Smog pump and all. I believe it is factory bumper that was repainted. I will shoot more pictures when I get home from xmas.
Also, is the master cylinder that I replaced of value as an original part? No matter what I do I plan on keeping original parts if useful or of value
