engine mount thread size

[blue-max]

My engine mounts have suffered a bit from corrosion on the threads. I'd  like to  clean them up properly. I think  the best way  to  do  this would be to use a dye. I think  the mounts are 16mm . But what is the the tread spacing. My guess is 1.0. Would like this confirmed before I go  and buy one. Engine is VP TMD22P-C 78 hp
