If i use corvette accessories, will i need to change my harmonic dampner also to corvette?

Thanks

 

My notes say the F and Y body hubs were the same for their respective years. Now, the pulley seems to be different.

 

What couldnt be differnt about it that would require a switch?

 

The spacing, in or outboard from the engine (to align it with the other accessories).

 

The balancers are different, the hubs are the same. The vette balancer is thicker and it moves the area the belt rides on farther out. I have one on my car. I switched to vette accessories for A/C purposes on my swap.

 

ok thanks guys, exactly what i needed to know.
