British Columbia.....mmm, try and find a wrecked Jaguar sedan.
Don't know how common these are in the States, but as we have learnt here in Oz, they bolt straight in and cost next to nothing.
Others we are using are from Mitsubishi 2wd utility's.
Double wishbone, disc brake etc. and the right width.
In fact most Jap import stuff seems near on the right size to fit earlier trucks.....cause being jap they are naturally smaller than the US stuff.
Check out the webshot photo's of the Jag front in my '36.
