That's what thought..........Mr.Gasket kit only comes with two springs, of which only one fit my application. Ended up taking the dist. and getting it totally recurved at a speed shop. Found out that the vacuum adv. was actually running retarde for the first couple of degrees and the toal adv. was not ther until 5,000rpm. now my advance starts at 900 rpm(instead of 400rpm) and is all in by 2,500rpm. Total vacuum advance was 28 degrees, and now is only 15 degrees. Mechanical advance is 22 degrees total. So, a total of 37 degrees of advance by 2,500 rpm.

Tech told me that my stock Motorcraft dist. is really one of the best and most adjustable out there. Seems to run much smoother now.
