First off, welcome to the sight. The best way to post pictures is to open a free photobucket account and copy and paste the image code into the post.
Put each image code on a separate line so they fit right. As far as the wagon goes, it wont be a big deal to switch to multi leafsprings because you are switching out the rear anyway. Multi leafs and a nice set of shocks will give you a better handleing car for street cruising. I dont know what kind of shape this rear is in so have someone take a look at to see what it needs. When I took mine out for rebuild I sprayed engine degreaser all over it and wire brushed and rinsed all the gunk and loose paint off. I did it a couple times so the paint would stick. Then I covered it with 2 coats of POR-15 paint with a cheap brush and when it dried it looked pretty good. Try to get some pictures posted so the guys know what you have going on. Good luck
