Thanks, good idea.
Is the rubber part 2 pieces that meet in the middle so you just cut one of them?

I didn't bend the ZF frame mounts. I cut 1/2" off the mount - the aluminum part. It's a super thick mount. It doesn't need to be 2.5" thick.

the early single-point ZF mount can be so easily modified. If you want
to shift the whole powertrain backwards just a little, you can redrill
the lower motor mounts towards the back. Doing this up to about 1-1/4"
will not require modifying anything else including the exhaust. You
will have to adjust the shifter down on its support near the left motor
mount, and on some cars, the upper bay brace bar gets close to the
external slave cylinder bracket. Our late '72 L mounts were drilled
with two different patterns so its mounts were not specfic side to side
like earlier ones.
For both of these mods, you must bend the ZF rear frame tabs backward
into shallow S shapes and remove all the rearmost transaxle shims. This
may reslant the carb so pay attention to your float heights. You'll be
shocked at how easily those frame tabs bend. Water pump pliers and a
small hammer are all you need. 3/4" is enough to allow big cap
distributors to easily clear a stock firewall. To accommodate big-block
engines, Bob Byars used to slide the powertrain about 4" backwards,
which caused the ZF to touch the A/C shroud & need a dent. That much
movement caused lots of other little clearance mods & required new
motor mounts. There are over a dozen such Panteras- Forest Goodheart
has one.

I know this has been asked before, but is the mount location support
to
move the motor forward or rearward?
Thanks,
Ken
