Hi Barners. I have aeroquip braided lines on my early flathead with an ID of about 1 1/4 inch. Is there a thermostat that I can insert into the hose that will fit this ID or one that I can cut down to fit. It seems to me I saw a thread about a Datsun 240 or 260 thermostat that would fit. I have checked the threads but have found nothing... Thanks in advance..
