Steve, My 2 cents: on my 1950 3100. I removed the front bumper, grill and radiator core support. I left my 3 speed tranny in truck...slid out old 216. Put 1959 235 right back in. I only "broke" a few of the clips that are on the grill. They have replacements at your local Auto Parts Store.. it was pretty simple. Take your time. Bag & Label bolts & nuts. The only time consuming was re aligning the fenders with the core support. Just take your time and DO NOT Tighten the bolts until you have both sides all bolts started. Todd
