Hood Torsion Bar hinge rollers

If you got them, is there a way to put them on? I got a 65 and will have to look at them.

look here, they are not seperate, but part of the "bar 15-19-46" http://www.jholst.net/65-parts-manual/hood.pdf

A cool alternative is gas charged lifts, just mount them so they attach at a stiff part of the hood
