[DeTomaso] Brass bypass flow restrictor-need one.

[Tony DiGiovanna]

FWIW, after installing any restrictor, delete plate, freeze plug, etc, I
recommend putting a bead of JB Weld over the interface.  
Some water pressure acts across the plate and could push it out.  I have
found dislodged plates in used engines.  I take no chances.

You have several options. 
First of all, if the water pump mounted on that particular engine does NOT 
have a bypass channel cast into it- such as the Weiand 8209- then you CAN 
run a Windsor thermostat with no brass washer under it, with no ill effects.

Many aftermarket water pumps do not have the channel.
Second, if the engine's waterpump DOES have a bypass channel, or the owner 
wishes to return it to more-or-less stock but you can't find a replacement 
washer, the brass washer under the 351-C thermostat can be approximated by 
using a 1-3/16" Dorman freeze plug and drilling a 3/4" dia. hole in it.
Dorman 
products are sold at all NAPA Auto parts. Be sure to deburr the drilled 
hole and deeply chamfer the edge for a lead-in to help guide the thermostat 
thimble.
Third, D Quella sells a block-off disc with no hole for those that want to 
run a Windsor thermostat. He may also have the disc drilled- dunno. And most

of the Pantera vendors have junk Clevelands around and should have used 
stock brass washers available. Good luck- J Deryke
