Hi, I've had an Eastwood inline flaring tool for a few years now, and I'm really happy with the way it works, but I want to make some AN lines(37 degree flares) and Eastwood doesnt have any 37 deg dies for their inline flare tool. If someone here has a newer Mastercool inline flaring kit, could you measure the external dimensions of your dies? they certainly look like they might fit in the Eastwood tool, but Id sure hate to buy their kit and find out it is too big or too small. TIA , Neal
