Newbie Needs Help....

In 1999 I purchased a speaker kit from Audio Concepts (ACI) in La Crosse, WI. The kit was built around 8" Vifa M21WO-39-08 woofers and Vifa D27TG-05-06 teeters. The company is no longer in business and its web address is no longer working. It is my understanding that the owner Mike Dzurko retired about 13 years ago.
I'm looking for the assembly instructions and, more importantly, the cross-over design as my speakers were significantly damaged in a recent move and I would like to rebuild them. I have been able to source replacement speakers but need the assembly and crossover designs.
I have included the website page image from a WAYBACK search of their old website dated January 29th, 1999, but they did not post on their site the crossover design.
