66 Plymouth Valiant help!

Thanks for the chart, forgot about it!

I thought about putting a ford rearend in, but ultimately decided that I'll try to keep as much of it mopar as I feasibly can.

@ Charlie - So, by happenstance, I was around the front of my car and I saw brake rotor through the poverty rims. I bought the car on the understanding that there were 9" drums all the way around. So I have disk brakes on the front already, with the stock widowmaker pot, and I also found the proportioning valve. Can't tell what the bolt pattern is since the hub caps are on and circumstances are preventing me from doing anything to the car.
Don't know if the spindles/control arms/joints are the same, or if it was yanked off of a later A body, so this car will have to come apart at some point.

I should mention that I bought the car on the premise that the previous owner was knowledgable, and now I'm finding all sorts of things out that neither of us knew about.

As far as the rear end goes, I'll probably use a narrow B and big wheels, since I'm going the route of making this a big dumb hot rod.

@ Red Fish - That is encouraging, but with my luck, I'll need to get it changed eventually.
It's all coming out. Eventually. I may be dead by then, but I'll be halfway there.
I'm documenting all the parts that are going on to it, and then I'll compile a final list if/when I sell it. Hell, it'd be good to just have around.
