Trying to get my hands on a set of the power bolsters that they put in the late model 311 and 357, and also in all the 303's and 336's I think. Doesn't matter what shape.

Scippy is selling a set not power just spring loaded by a actuator[ATTACH=CONFIG]536158[/ATTACH]

Sorry you already have these in your 311.

Look at Pier 57 website, they have some out of a formula. Not cheap

I have a pair that are white with red inserts, vinyl is perfect $1800. If interested call or text me 508-631-4784
