Hey everyone, this just in. Spoke to Koni and they do not make shocks for the '89 year. Looks like I'm going with the Monroes and will see how those go. Once I establish a repeat business relationship with this RV mechanic, I'll be more creative when it comes to purchasing my own parts and having delivered to their shop to avoid the high markup. Also, I understand you sometimes have to pay the premium price to get the parts locally (vs. searching online and it taking longer to ship).
Per the mechanic, the Bilsteins of yester yore (made in Germany) are gone and they are made in Mexico? But couldn't seem to tell where Monroes are manufactured either. Their parent company is headquartered in Long Beach, CA FYI.
You guys are the best. Thank you for all your help on this decision! I won't hold you liable. haha :)
