Pulley Spacer?

I have to get a pulley spacer to set them all in order. Its a 351w. I just bought the march performance pulleys set. They tell me I need There spacer. which is .938 heres the link. http://www.summitracing.com/parts/MCH-1434/ now I have found one for significantly cheaper here http://www.summitracing.com/parts/PFS-81007/ I know it is .012 bigger and I can make it smaller. But does it matter what brand spacer I use. As long as they are the same bolt and thickness.
Thanks All

order both, then return the one you can't use.

 

Anyone know about this?

 

I see a difference in quality. What quality do you want?

 

The quality doesnt really matter. I just want to make sure theres not a difference in how it will work.

 

I really don't think it would matter, I prefer the flat style ones myself, especially if I have to cut them down but both would work.

 

Cool,buy the cheap one then.
