Hope this works. You are looking at a 1959 Chev 261 into a RH drive Chev military 1940.
Installed a YF as per CarbKing and love it. Had a 3/4 inch steel adapter home made to facilitate the installation of additional vacuum lines for the wipers, PCV and vacuum gauge.... it is actually a crude repro of a stock item for that period.
Now look at the clear green nylon line. I had to use a steel reducer...... a male to male brass into the T fitting and the heat sender to an after market mechanical gauge. Everything tightened snugged with plumber's sealer paste. DO NOT OVER TIGHTEN ....... this was during the testing phase and we had a 1/4 turn valve inline that we could shut off the steam return line.....run the engine.... then open the valve and see all the air bubbles/froth purge itself to the radiator. Eventually all the temp rubber/nylon lines we replaced with solid flared steel lines.
Top speed 44 MPH at about 2900 rpm........ or half that in Low range 4x4........ and yes it whines like a banshee......cruises nice at 25 to 30 mph 23/24k.
hoping that the greatly reduce photo comes out OK.
