Hi, I have a 1990 Toyota Pickup 2wd, 22R (carb). I have been looking all over the web for the correct harmonic balancer but can't seem to find it. I triple checked part numbers and I still ended up with a balancer with double v-belt grooves. Do I have to order one for an older model year to get the serpentine belt groove? Thanks for the help.

 

Just to add some more information, I don't have power steering or A/C. Here's some pics, hope they help.
