[DeTomaso] Motor Mounts

[JDeRyke at aol.com]

Trip, Pantera motor mounts are in two parts. The bottom section that bolts 
to the chassis are all the same left to right and early to late. The top 
halves have offset holes- or on some Panteras, two holes. Our '72 L had one 
offset hole on the right side and TWO holes in the left side top. Documented in 
a POCA article many years ago, I reversed only the upper motor mounts 
left-to-right and slid the entire engine/ZF back 3/4", gaining enough clearance 
to run a big-cap Duraspark distributor. Nothing needs to be disturbed in 
doing this including wiring, fuel and even the exhausts. The rearmost sheet 
metal ZF mounts must be bent into a shallow 'S' and an extra 3/4" thick spacer 
provided to fill the new gap between the ZF mount tabs. 
In your case, you can probably gain your alt-clearance back by slacking off 
on the two ZF mount-bolts in back, slacking off on the two long connecting 
bolts holding the engine mount halves together, and slacking off on the two 
bolts per side (4 total) holding the upper motor mounts to the block. Do NOT 
remove any of the bolts completely. 
Put a board under the pan and jack the engine up until the block is ALMOST 
clear of the mounts, then pry back between the frame and crank pulley for 
clearance. When you've gained as much clearance as possible, lower the engine 
and tighten ALL the loose bolts. You'll likely gain   about 1/4" clearance 
in doing this, and no more alt-to-firewall noise. Good luck- J DeRyke
