Richard,
Are you sue you have a T-85? The T-85 wasn't intoduced into the Ford line until the 56 Thunderbird with a 312 engine. It was used in the full size car and the T'bird, with and without OD, in 1957and up to at least 1962.
Did you install the T-85 after you got the car? Many cars were changed over the years as it isn't a difficult conversion.
You may want to verify your transmission if you are not sure. There were three BW transmissions used with a Y block foom 54 and up, the BW259, the T-86, and the T-85 and all three were built with, and without OD.
Hurst had any number of kits for them. Some kits used Mystery shifters, others Synchro Locs, and Master Shifters and of course an OD required an OD kit. I'm sure some Hurst equipment collectors have it figured or have the catalogs to do it, but the bottom line is still the same. There is very little of it left.
After almost two years of looking I have given up and am going to build a mount for the MasterShifter I have.
If you do have a T -85 you also should verify which tailshaft you have because there are at three different lengths and two different mounting methods. I am not sure which bracket Daniel wants to replicate, but I believe it's the one he shows in Part 10 of his restoration blog, even though he shows installed on a BW 259. It's a heavy bracket and it requires a second bracket that uses one of the solenoid bolts for attacnment.
If you do need help I can help you ID your transmission, I have pics of all three and also of the tailshafts.
I have posted the links to Daniel's info and the info he posted in the H.A.M.B. "That HurstShifter Thread"

Note that the instructions fo that kit have 5556 in the number. I believe that means that the kit fits aT-85 with the tailshaft with 4 short bolts. Most tailshafts from 57 on up use 3 short bolts and one long so they require a different kit that contains the heavy brackets in Daniel's Part 10.
I am starting on my bracket now and I am using Daniel's bracket pics in Part 10 as a guide.
