Drone.... thanks for posting that! One sure fire way to turn folks off is to be overly outspoken! I am a member of several forums and like the ones that folks are helpful, want to share, enjoy some good clean fun, and have a good classified section. Thats 1 of the reasons I joined them to start with.
Heres a thought about our Original poster... Are the Blocks they are referring to actually raised or larger lift perches?
Or, are they actually blocks on top of the perches? (If they are I would suggest they be welded solid to the perches for all of the safety reasons previously mentioned above. Or... remove them and look for alternate ways to acquire the desired lift. (maybe a small body lift.)
There are some companies now making weld on perches larger than 1.5".
Sometimes terminology differs and can mess with our being able to provide an adequate answers.
