Heat shield for MC

Thanks for looking!

I got a master cylinder heat shield for my 69 swinger from Mancini. The car uses a manual master from a 73 dart with disc brakes, so four bolt. The shield hits the firewall, so a good chunk needs to be cut out of the bracket and shield to make it fit or try to pound out the studs that hold MC to firewall and use shims with longer bolts.

Any suggestions or advice are welcomed
