My first 1972 looking for answers

[crimson red]

Just buoght my first 72 Chevy super cheyenne 2wd auto. SB / Tach / tilt / AC / truck and trying to find out what is and not correct pieces on this truck?
It has a 3 spoke steering wheel ( maybe from a corvette style alum. spoke with plastic wood grain looking wheel ). Was that an option in 72 or should there be the Black 2 spoke I've seen on other trucks . The truck does have Houndstooth int.
What is the correct width of the rims for this truck ?
Should there be the tower style hose clamps .
For the heater hose should it be the 3 rib style , or the GM stamped hose.
And for the radiator cap what pound rating should it be( I've seen 13 and 16 )

Thank you Crimson red
