also, as far as axial play when adding shims, how much end-play do you want?

Although not a quantitative answer, hardly any. Everything I see says, "eliminate axial play".

How about not so tight that it binds the shaft or advance plate. The mechanical weights are independent of the shaft and shims.

The springs for the VJ4BR8 and VJU4BR8 are the same.

thanks glenn, that explains how a guy over here used to modify VJU4 BR8's for mechanical advance only on performance engines back in the early-mid 60's.

are the springs the same between BR8's and BR25's? i know the weights are different.
