I would just replace it......if it the original, the 42 year old pickup coil will probably fail soon.
Rock Auto has replacements from $40 exchange to $125 for brand new.......
I recommend you put a Mr. Gasket curve kit in before install and set timing via Lars papers.

Which kit jebby? I believe there are two Mr Gs. for the SBC. One had poor feedback / reviews about sloppy bushings for the weight pins, the other kit was ok. Don't remember part numbers.
Anybody make better recurve kits for the O.P.?

Just replacing a stock part because "it's old" is not a good strategy. The stock dizzy is fine, if it's in good condition. What to look for?
free rotation of shaft; very little side-to-side movement of the shaft in the housing; free action of the mechanical advance unit; little (less than .010") axial movement of the shaft in the housing; no damage, cracking, or excessive wear on drive gear or other 'working' parts; tach drive parts in good condition.
Other than that, it's clean it up, lube it, replace the vacuum advance can and put it back in. Convert it to electronic ignition (Pertronix?) if you have points [although I still have points and am very happy with them].

Add distributor gear shims to the bottom in an effort to reduce end play. My money is on the end play being super sloppy. Otherwise check for advance mechanism wear. You would want to preserve the factory weights if they are still serviceable.
Most HEI re-curve kits leave much to be desired. Found a decent re-curve kit but it comes packaged with a bunch of other expensive (but still crappy) parts you do not want to use. Maybe just try the new springs from a cheaper kit. There are ways to reduce available centrifugal advance if that is desired. Gotta work with what you can get.

Way back before we had HEI, we would do the conversion over to dual points for a performance upgrade.
I never see this option mentioned and was wondering if anyone does this anymore and if it would help give the guys who want to keeps points a performance upgrade option?

Standard Ignition makes just about any part needed to rebuild any HEI or Points distributor; company been around a LONG time.
Look up your parts in the link below and then find the parts wherever you might shop...local parts house or internet
Start by getting Lars papers on distributors
Shim the gear end play to around 0.010", replace the pickup, rebush if side to side play is excessive, you already know about the different recurve kits.
