Rookie needs suspension help.

I have a 28 Hupmobile Century6, model A which Im trying to build into a streetable car. I have a 89 Lincoln town car that I plan on using the motor/trans from. Question is, budget being the biggest issue. What do I need to do for the front suspension:

Use a mustangII? Ive got one tacked onto the frame, (cut out from a pinto) but I had to widen it about 4" to clear the frame rails. I need to buy tubular upper a arms to clear the fenders should I decide to proceed, and from what Ive seen it looks like 2 grand to finish up with new parts in this manner, and Im really not sure about the way it looks.

Use the orginal straight axle? I have the original straight axle and leaf springs. Should I use these? Axle looks good, but I dont know about using 80 yr old leafs. Should I use a hairpin set up or what?

Use the lincoln frame with its setup and modify it to fit the hups body on? Is this practical or not?

Thanks in advance for your time.

Hairpins are for single crosswise springs, the Hup has two lengthwise ones. The stock axle would work if you can find some kind of hydraulic brake setup, but I would go with a newer axle, a Chev pickup, for instance. If you don't trust the old springs, any spring shop can make you some fresh ones. Softer, flatter, whatever you want.
I'm not a fan of MII stuff. The Lincoln will have bits and pieces protruding from everywhere past your sheetmetal and look like crap.
The Hup is a great looking old beast, make a great tourer, lots of fun ahead for you!
