Q?: Hotchkis SFC's and GW Body Mounts

[77thor]

I've already bought my Hotchkis subframe connectors and I want to get the Global West InterLoc solid aluminum (stock height) body mounts.....

The question is.... should I get their standard mounts #800 or the mounts #809 they recommend for their own SFC's
What's the difference between the 2 of them?   Note: The #809's are $22 less.

Thanks.
