Also lists all classes that require aftermarket axles and retention devices..... basically anything 10.99 or quicker. Otherwise C-Clips are legal.

OK, thanks ! It appears that as long as you have any kind of posi unit, you can run even stock axles without C-clip elims, in the slower Stock classes.

2:11 REAR END
Welded spider gear rear ends prohibited in all classes. Fourwheel
drive permitted per class requirements. Aftermarket axles
and axle-retention device mandatory on Top Fuel, Funny Car,
Pro Stock, Top Alcohol Dragster, Top Alcohol Funny Car, Comp,
Super Comp, Super Gas, Super Street, and 10.99 or quicker E.T.
cars; also mandatory on any car (regardless of class or E.T.) with
a spool.

We've run low 12's and high 11's without ever breaking an axle. So do any of you guys in these slower classes run Stock C-clip axles ? Or is it better to at least buy some that are a little stronger ?

I assume that Moser axles are one of the highest priced. I see several axles that are said to be stronger than stock. So, for anybody with a low budget build, what is the cheapest good quality axles that would be plenty strong for a high 12 - low 13 sec Stocker ?

Do all 8.5" ten bolt car rears have C-clip axles ? Anybody know if the 8.5 rear in a '77 Bonneville would have the same length axles as a '71-'81 F-body ? Or maybe a '73-'77 A-body ?

Some say a '77 wagon might have some odd ball rear--not an 8.5. Anybody know for sure ?
