TTI mounts

Hi,I think that I will have to modify the firewall slightly mainly because i don't want start blanking anything off on the engine, i want it to run as it should do, i will be getting a remote filter set up and have used a Holley sump.
O so the holley sump worked with the tti mounts? Thought pitman arm hits it or something seen in one thread however maybe he made his own mounts
