I am coming here with high hopes that someone can tell me the fastest and most economical way to get a replacement harmonic balancer for my '90 4cyl pickup 22R....the balancer has two pulleys; the larger in back for a v belt powering the fan and alternator; a smaller diameter serpentine belt powering the air pump and AC. The truck was built in Nov. '90 and may have some '91 parts on it??? Everyone so far keeps wanting to sell me a balancer with two v belt pulleys.....I can provide pictures of the balancer I need, to confirm we are talking about the same thing.....

 

My truck has Air conditioning and Power steering. that gives me 3 pulleys.
Closest to motor is Alternator/ water pump
Middle is A/C
Furthest out is power steering I believe.
