Hi:

Does any other "point plate" fit the 62-69 Corvair  (Chevelle, etc.,) - the 
dwell on my 140HP keeps changing on a daily basis (new  points installed - I 
know ideally it's supposed to be within 31-34  degrees).

I noticed the vacuum advance rod vibrating back &  forth (at idle) even 
though the rod is securely resting in the point  plate.

I tried Dale Manufacturing:

But no one answers. I'm  debating between a new (rebuilt) point plate and the 
1162A electronic ignition  by Petronix...

Regards,


Tony



Tony - Jumping to the Pertronix is the easiest way to go. Both the  Pertronix 
Ignitor I and II come with a new point plate. With the electronic  trigger 
now replacing the points, there is no sideways pressure on the Vacuum  advance 
pivoting plate. (With points, the stock plate wears out faster when you  
replace the original points with the Heavy Duty models, because of the  pressure.) 
Dale Manufacturing does a good mod to the point plate, I believe  Wall's 
Corvair Underground sells them - I am sure he will answer the phone!  The modified 
points plate adds a bushing at the pivot point to lessen the  wear. The only 
other points plate that will fit the Corvair was the early Vega  71-73. It had 
several improvements over the original Corvair. Like most Vega  stuff, those 
are discontinued and long gone from the market. Of course all GM  in-line 
6-cylinder motors from 63-on - until the HEI replaced points, used the  exact same 
points plate as the Corvair - so they suffer the same fate. When  you install 
any new plate, be sure to check the hole portion of the vacuum  advance unit, 
where the pin on the arm on the pivoting plate drops through,  sometimes the 
pin will wear the hole out into an oval. Any extra play in this  relationship 
will cause jumpy spark!  I should add that the internal  parts of the mechanical 
advance area inside the distributor are subject to wear  and even breakage. 
Check them out - especially the pins that locate the advance  weights. I have 
seen them come loose. The inside of the distributor becomes an  efficient lathe 
and can cut through the housing. What a mess! - Seth  Emerson
