I'm sure they fit great, I wanted to buy a kit for my car as well, but I could only find two companies that even offered them for a 1954 Mercury.
The '54 Mercury was the first production passenger car with ball joints, the '53 had king pins. They design was new at the time and it was changed in 1955 to the style that you have. The '54 model was all to it's own and that makes it hard to find a company that sells brake kits. I have researched this for over a year with little results. So, not only being an upholsterer, I am a machinist with his own mill and lathe and it came to me to make something fit and be functional.
Another feature of doing this is that it all looks good and doesn't look aftermarket. I have had die-hard Ford guys comment on how it looks more original. I know the booster and master cylinder look way different from the '70s Ford truck, but they don't look aftermarket either.
I just can't wait to drop in the new '57 Thunderbird 312 and redo the upholstery for next springs car shows.
