Thanks Headknocker. They are kind of rare guitars, for sure, but not exactly in high demand due to the color. Of course, everyone knows that the color of the guitar has a huge effect on the sound and playability (Not!).
I had a 1988 Gibson Flying V in Antique White that had the same tremolo. I did repair that tremolo because I had all the parts. There are two issues with that tremolo system.
Issue #1 is the posts you mentioned. The posts are weak and bend toward the headstock, making the tremolo nonfunctional. The solution is new posts made from Stainless steel, and sold in Germany.
Issue #2 is the tremolo spring and the spring caps and post. The post is a threaded rod that threads through the spring and caps on each end of the spring. This rod strips its threads, which strips the threads in the caps. The solution is a full replacement with stainless steel as well.
Repairs for the Steinberger KB tremolo on that guitar cost me about $80 just for the 2 posts and the tension adjuster. I since sold the guitar to a guy in Russia.
The stop tailpiece solution for the Lite Pro 1 was the best option for me. Since I build guitars here at Overacker Guitars, I was able to easily make the repair. Plus, I tend to avoid tremolo guitars, so the stop tailpiece made sense for my playing style. It sounds and plays great, so I will keep it for a while.
