Bruce should be able to tell you what to do with it. I know they will need some shims. Weather it's 3/8th's to 1/2 inch. I have the front chassis off of a 69 Chevelle on my 37 Pontiac. I know some of my shims were rusty and I believe I don't have enough in there now. 7 years ago when I did my GTO I put the shims in a bag and marked them. When I put it back together it worked great. Still haven't had it to an alignment shop. Seems like no need for it. Someday, maybe. I'm hopeing I don't have the same problem your having with my 37. Keep up on this thread so maybe I can learn what to do with mine.
