need help with stock wheels

[BUGMAN II]

got a chance to buy some wheels. owner says they are 67-70. they look the same as the early wheels to me. can I run 64-66 style hub caps with these? owner wants $125 for 4 stock wheels. is that a reasonable price?

is there a thread somewhere that makes sense of all the different 6lug wheels and hub caps and what will work with what??

my dream set would be 15x7 front and 15x8 rears that I could put the stock '64 hub caps on.

here are the wheels I have a chance to buy
