L36 belts and pulley help
Hey everyone
Have a 69 L36 with just alternator. (Had smog)
So 2 fan belts.
1. That goes from crank to water pump with no tensioner...... A 15320 in Dayco and other brands,.. an 7320 in a Gates. Is that correct?
2. That goes from crank, water pump and alternator. Dayco 55345,... not sure of Gates number
Are those right?
Also,.. my 2 grove crank pulley has a slight wobble. Would like a used one in good condition. Not restored,.. just something that looks appropriate for a well maintained 50,000 mile car.
Thanks in advance for any help.
Also,.. should harmonic dampener be painted? Over-spray? Black?

I can't help with belt numbers but I'm pretty sure every 427 in 69 came with the 3 groove pulley regardless of wether or not all grooves were used. Also I think power steering used/shared a pulley.

My 72 LS5 (should be the same?) 3 groove wp pulley, two groove crank pulley
Crank WP Belt 15315, 11A0800 Dayco TopCog
I've got power steering so the alt belt is totally different

The water pump pulley was 3 (third one for the Smog pump).
So I have 2 on crank, and 3 on W/P,.. the front most one not being in use.

Top-cog belts just look wrong to me (and are of course),.. so I was hoping to at least get something like a smooth Gates or Goodyear in there. Perhaps if I'm patient enough,. even spring for the repo GM ones.
