Convert to 4 core Radiator, What's Involved?

[Ironhorse]

One thing leads to another on these old trucks. My current radiator I pulled during the std. to auto swap is in bad shape. I have a good original 4 core I had put back for a "later date" which I guess is now. Besides the obvious mount differances what else is involved? I have the upper mounts/rubbers and a spare pair of upper mounts/rubbers which I plan on removing just the saddle portion from the actual mount and bolt the saddle in place for the lower mount. Any issues with the shroud mounting or the radiator support needing mods? Radiator lower shroud clips differant? Should mention this is on my '71 4x4. Sitting at home right now, truck is at the shop and radiator is being pressure & leak tested and repaired as needed so can't make any real dry fit observations right now. Any and all help appreciated.
