Thanks to Jack Huisinga for sending me the description and photos of installing Showa 54565-97C air shocks on his V1000 I-Convert. In Jack's own words:
The Showa 54565-97C is standard equipment on some Harley models and many riders replace them to lower the rear, so the 54565-97Cs are regularly available on eBay at reasonable prices. The shocks and are equal or better than the Convert's original rear shocks (MG# 13550241) and are much more easily adjusted for load (with a hand pump), the adjusting the original shock with a wrench that you can't get on the shock without removing the side bags.
The 54565-97C shocks need to have the bushings driven out of the eyes. A socket and extension works well as a driver, a heavy hammer swung easily provides the needed force. The trick is supporting the eye while driving the bushings. I used the brass liners I made for my bench vise. You might want a new set of shock bushings (MG# 18551650).
The 54565-97C has a larger diameter than the original shock and it interferes with the brake caliper Bracket (MG# 17635350). The arm on the bracket that supports the upper / front caliper mount needs to be thinned by about 5 mm leaving it no more than 15 mm thick. I cut the material out on radius but if I were doing in on a mill the bracket could be thinned to 15 mm all the way to the end of the arm.
I purchased a Progressive Suspension Hand Air Shock Pump 30 PSI Gauge to c. I have found that 20 PSI is sufficient for riding 2-up with luggage.
