The info was in reply #3. {above}
JDM said; I am using Norms lowering link rocker, it is very robust and bullet proof. It is not however, adjustable, but I would recommend it. Here is some info for Norms link. Phone # was 281-339-1156 and email was Sanleonster@gmail.com.
Many have used Norm's Lowering Rocker over the years {including myself}.
He offers them in many sizes. (I think from 1" to 3" drop")
Bearings are included.
He {and I} recommend the 1 1/2" drop.
NOTE: If you lower the rear you must also lower the front to keep the settings of the bike's geometry almost the same as original.
Ride safe, Ted
