The version being sold by Dales Cuda shop is not correct for his 72 Thermo-Quad but rather is a correctly shaped replacment unit for the popular and rare DR1114429 solenoid. I've purchased the Dale's unit for customers who wanted one but you should be aware that they are not as strong as originals and often do not work properly because of it, (see attached photo comparing the internals). They also lack the all important DR1114429 part# stamping. See photo in next post of a correctly stamped original.
