Just put on a gsr brake booster on my 92 eg hatch since I'm doing a full gsr disk swap with the 1" master cylinder. The gsr brake booster is bigger than the eg, so it won't line up the same. It doesn't sit flush with the firewall as the eg one does since there are grooves to allow the brake booster to sit flush. .Will this be a problem?

 

Nope i reamed my holes a tad and mounted, made sure not some crazy angle and rocked out
