I got my 200ci head for the 1966 mustang back from the machine shop and installed everything. The machine shop removed the sending unit. I have ordered two from Oreiyles for my car and both were the wrong size and thread. one was a 3/8 and the other 1/4. I found a brass fitting that went in and it was 1/2 by 18.. Anyone know what sending unit works for the 200ci and where to get it?

That is the weird part.. This is the stock motor. It is definitely a 200ci head. When I picked up my first one at Orielly's, they sold me a BWD WT913 which is a •3/8 Inch x 18 MPT.... I went back and they order the other one listed for my car and it was a BWD WT907 which is •1/8" x 27 MPT. Neither one fits.. one is to big and the other is to small

I need help finding the right one..
 
One is 3/8".....one is 1/4"......the size you say fits is 1/2"......just looking at some of the on line stores, it appears they are all the same, 6 & 8 cyl. There is a change about Sept. 65. I would get out of the local stores and get with a Mustang specialty shop.
