Using two stock light springs in distributor advance, good idea?

Really depends on what spring you have in there. Tons of different oem ones. Also what is the advance cam that is in there now. Should be marked say 10R or so. They are all over the place in those years. seen 8 and 18! Got a distributor number I can get the specs. Those Mr. G springs slam right in say at 1500 or lower.

That's what I've heard and why people only use one spring from the kit. I'll have to take apart the new distributor and look at the plate. My old one had about 35 degrees of advance built in so I'm looking forward to this new one plus not having to mess with the points anymore.
