Gentlemen, Thank you all for the inputs and re-directing me on the ends. Looks like the Red Caboose 7003 body will do the correct sides for the 8501-8750 series. I also see that Detail Associates makes a pretty close 4/5 Dreadnaught end for me. Hope its close to the correct height.
Ken, you'll need 4/4 dreadnaught ends for the LNE cars.
Tom Madden, remembering when the Alpha cement plant yards was full of 'em.
