Change chassis/ transplant/ or new parts???

[Larry S]

Hello folks. I hope all are well. I have a 1969 c10 that my grandpa bought new. Several family members owned it after his death in 1984. I ended up with it in about 1998. I'm not going to sell it. I disassembled it in in about 04. My question is... its 1969 with 6 lugs drum brakes and I have a nice 1972 5 lug disc chassis. Should I just use the entire 72 chassis for my build? Or transplant the 5 front end parts and 5 lug 373 gear rear end to the 1969 frame? Or should I buy new front end parts and swap rear ends from the 1972 to the 1969?
What's my best option?
Thanks in advance.
