fire wall does not match frame

[wbs]

hello again
i bought a model A 30 roadster in pieces
i complained to the Barn latelty that sills/rails did not match frame
now am in the process of installing firewall and :
throttle foot pedal wont clear bottom of firewall
and clutch pedal wont clear bottotm of frewall

should firewalls be the same for all roadsters? has anyone else encountered this and did they solve the problem by cutting into the frewall?

by the way, i think the rails were from a 32 ford but don't know for certain.

the picture of the throttle foot pedal stub not clearing the firewall was difficult to show, sorry
