suspension swap question.

Ok I dont know the specific details on the year models of the two cars I have(I forgot!). They are an hour away at my farm.

I have a good car with all good suspension and lots of good parts that looks like this

I also have a car that looks like this that is pretty much a shell. It doesnt have a hood, Front suspension except for a bare K member, Has no rear suspension. However it is a factory standard tranny car, I still have the Clutch Pedal parts

I would rather have the standard, The second cars body style, And would be willing to put the extra effort into it.

Main problem is title. I cant get the title to the first car, I have the title for the other one.

So how much of the first car can I use on the second car. Main two things I am concerned with is the Front suspension, and the windshield. Some parts such as torsion bars will be replaced with either car. The rear end doesnt matter but I would like to get as much of the rear suspension off the donor and use it on the other just to get it rolling.

I am not looking for a complete list, Just wondering how much will swap. I do want the larger bolt pattern and Disc brakes off the Donor car.

Is this even more than its worth.
The way I look at it is that it will give me more of a reason to go through the suspension and such to have a better car in the long run. Both cars are solid as far as rust and such is concerned.
Thanks
