Over center spring

I ordered a new setup for one of my cars from Brewers about a month ago, picked it up at Carlisle.

I did mention that I wanted the stock type that keeps the spring & I went with Dan's recommendation.

Since you have a bad knee.... the cars I drove with the alleged 'newer is better, just buy it and remove your spring' setup required a LOT more leg power.

Odd release / engage points too, PITA to drive overall.
