Nice Chewy. With the alternator bracket being on the bottom you will not have any problems with the radiator hose.
Just for the record what you are calling the "under dash supports" aren't really intended for that purpose. They are designed to be used for mounting donor Mustang headlight and flasher switches which is why they need to be bent or modified to get repurposed as dash supports. I see you found the switch for your hazards! I like your dash material...Installing under dash supports. Anyone else find that you need to bend these a bit to work? I installed a momentary push bottom switch in DS support for my hazard lights...
I might be mistaken, but doesn't the radiator sit in front of the steering rack?Lots of folks have removed & reinstalled their drive train on a completed car. So with some forethought & bringing the hoist in from the side, the radiator will not be a hindrance.
If you do bring the hoist in from the front, I found that the limit to forward movement was the steering rack. The radiator was not a factor.
I already have a piece of cardboard taped to the front of the radiator. Did so per Breeze instructions to keep metal shavings out of the fins while drilling.Once you install the radiator, cut a piece of scrap board and place over the front of the core. being that the radiator core is as soft as butter, it is so easily damaged, especially if you're going to put your engine in afterwards.
I also fabricated the lower mount. Some of our roads over here are pretty ordinary so I wanted to give the radiator as much protection as possible. I used rubber isolation mounts and so far they have worked out well. As an aside I found the car handles the bumpy roads better than I thought it would.
Your build is progressing very nicely, sounds like you had a lucky escape with the cut off wheel! I have been bitten by these before. Don't reckon I have used my 9inch grinder since. No one needs an unnecessary trip to hospital right now.
You are going to have a great car when done.
