Front stuff all looks stock ( I though it may have had been changed ) --with exception of the coil springs , they do make parts to interchange the brake/ front end parts

I had one of those kits at one point but, gave it to another guy --I don't think he ever used it however .. I clipped my Desoto --it was a lot of work
the interchange they are takling about is putting a volare front on I'm sure ..that is again a bunch of work and fab skills and tools

this is a guide for your rear you have in the ca --see pic
