Thanks for the quick replies and information. This helps a lot. My feedback:
1. 216 - I may have misstated on this, given it's been 21+ years since we brought it home. I defer to those more experienced than I am. Unfortunately, I didn't take pics or document the as is setup of the truck, and how things were installed when we took possession.
2. As work progresses, I'll take pics to document how we're doing the work. I've engaged a very experienced local mechanic and fabricator to do the lion's share of the restoration so will have more info on the mounts soon. As memory serves he'll use the front mount/crossmember and weld mounting points to the crossmember that's under the cab.
3. Same as above with the water pump. I've purchased a new 4 row radiator which should go in soon as the mech finishes up the front end.
Overall, we're learning a lot along the way. One discovery is that some parts are passenger car specific. That's added some time, cost, and complexity to the project. Also, my selection of the 1953 engine added some difficulties as a later 235 would have allowed for more "plug and play" interoperability regarding the transmission, etc. Regardless, we're making progress.
Again, I appreciate the information and will update later.
