What's wrong with this K member?

I like the spool mount especially with a 4-spd. Getting hard to find good quality biscuit mounts these days. A couple good burnouts will rip apart most of todays crappy mounts on the left side. Ploylocks are getting harder to find. SB spool mounts are available and can easily get poly inserts. Will never break one of those. Maybe with supermega horsepower.
