My '53 3100 had the original rear mount removed but no cutting to the
firewall. My engine has a plate bolted to the front of the engine which has
the appropriate weldments to allow it to sit on the original engine mounts
(I think). There is one transmission mount just behind the shifter
linkages. There are no other current or old cross members to support drive
train assemblies. If there were any originally, they have been removed. I
have a Saginaw 4 speed transmission.

Hi Paul,
Yes, you will have to do some cutting. On my '50 we had to remove the rear
engine crossmember (right under the firewall) to get the tranny in. We
welded a bracket to the original tranny crossmember (farther back under the
cab) for the tranny mount, which works quite well. We still needed to move
the whole works up a little so we trimmed the lower part of the firewall up
about an inch. This was up to the slight raised bead above the tranny
floor pan. Presumably we will still be able to get the floor pan sealed.
This gave me plenty of clearance. I didn't use the bisquit motor mounts so
I don't know how these may need to be placed. Hope this helps.
