After reading all of the threads per Cliff, and the WAZOO suggestions, along with a lengthy conversation with VetteVet (Jep) last night, I have decided to block the TB coolant. It makes sense and even though I live in the NE, I really don't drive the Z during the winter that much, especially with any salt on the road. So it's really no biggie.
That being said, went out this AM to pick up the items needed to complete the job. Although I have a rethread kit, the instructions specifically say it is not to be used to cut new threads. And it even doesn't have the correct size tap anyway. So off to HD, and Lowes with no success except I did pick up a 11/32" drill bit just to be sure. Their tap and die sets, even single 1/8" NPT taps are non existent in these stores.
So off to Fastenal to see what they had. Found the correct tap and T-handle wrench there and the brass plugs needed to do the job. Only problem is the first two items were very expensive....the brass plugs for a bag of 5 were only $2.17, a real bargain. I won't tell you want the other two items cost. Found on ebay that I can get an 80 piece set which includes the
1/8" x 27 NPT tap, for less than 1/2 of what I paid for two tools. So they will be going back for sure.

the brass plugs...

the other two expensive items..
