Car is a 56 sunliner, 292.  I have a '57-style distributor and edelbrock carb.  The car has always felt a bit sluggish in throttle response, and after reading on here, I bought a set of different advance springs (Mr Gasket, maybe #925D or similar?  Dont remember exactly)...with hopes that they might make the engine a little peppier.

Well, this past weekend I had the pass side of the engine opened up to replace an exhaust gasket (another question to be posted in a different thread) and I decided Id open up the dizzy to swap springs.  however, when i opened it up, i couldnt find any springs.  The breaker plate that the pertronix unit is mounted on moves freely with the vac advance removed, but i cant see any springs anywhere.  Are they under the breaker plate?  do i have a vac only advance distributor?  I didnt want to pull the dizzy out and find out i dont have springs.  If it is vac only, should i get one with vac and centrifugal advance?  If so, any recommendations?

Any thoughts are welcome!
