54 Crestline disc brakes, again

[emf]

I searched this forum for answers, but was unsuccessful, so if I missed it, sorry.
I have a stock 1954 Crestline Sunliner and wish to install manual front disc brakes. I have seen many kits available and all but one I have looked at say 'must use 15" disc type wheels." Since I have Coker's bias look radials at a cost of over $1500, I must use the original Ford wheels. An ebay item advertises 54-55-56 kits that use original spindles and wheels but the caliper needs a bit of grinding. I have asked the seller to elaborate. Prestige Thunderbird has a complete kit, but he says 54 spindles were 1 year only and I would have to convert to later spindles to use his kit.



Is anyone familiar with the ebay kit from MGCHEVYPARTS?
any insight from you guys that have done this?
Thanks in advance
