It does have spring mechanism set up below you can see and I can turn with a screw driver -

google search is showing for sale ad's - 273 - 318 - 340
cannot find a chart ?

if this was a dual point - in the parts bag is only 1 point -
person I bought car from had this in a box apart ???
dont know why he would ?

should I look for a second point before I attempt to sell this?
