Just to clarify...I personally don't have any knowledge of what heaters were used in the Darrin cars, so I can't claim that this elbow I'm having reproduced will fit that cars heater. The heater in my HJ is the 100171 model and uses the elbows of concern. Of course, the part number/s in the parts book (there are 2) is for an elbow with flex ducting attached, and I don't know if there is a p/n for the elbow by itself. I don't have a Darrin parts book, so I don't know what heater/s were used.
Please advise/confirm that the Darrin did/didn't use the 100171 heater so that I'm, at least, straight.
Thanks,
Shel
