IRS knuckles

[RuffIndustries]

Hey guys, so i'm here to pick some brains. I'm currently working on an automotive project that will require me to put together a double wishbone rear suspension. While in search for components I came across this forum and the use of the T-bird IRS uprights/knuckles. I see the knuckles are still available for purchasing new. My concerns are the knuckle being to large for my application and the hubs being a ford 5 lug. My plan is to use a 13" wheel with honda bolt pattern and brakes setup. The car will also be FWD so I wouldn't utilize the shaft holes. Would anyone have any information on someone using these for a universal setup?

Few issues id have to hash out.
1) finding a source for a hub i could use with a 4x100 bolt pattern
2) getting a honda caliper mounted to the knuckle
3) finding the measurements to make sure its not to large.
4) producing a lower and upper arm for my application.
