Interesting stuff ! I see you notched out the bumper support, how clever.
You're doing some nice work Paul ! I have been hacking away without a plan so far, so we'll see how it ends up !!
I's also kinda neat to see how 2 individuals proceed down a similar design path ...
Hey, I FINALLY GOT PICS !!!
This shows how I notched out behind the bumper support to give me a little more rad clearance for height. The rad will rest down further and more forward than if I placed it on top of the bumper support between the frame rails.
This next shot shows how much I gutted from under the dash. I'll need to refab the EBrake bracket at the top and plan to reconnect the fresh air inlets to whats left of the stock ports, i wanted to preserve the location of my Ambulance fans ...
This next shot shows a frontal kinda shot to show the amount of material I cut away. I probably should have cut a lot shorter from where I did ( you can see the trace of the mexi rad position in marker on the nose. The previous Mustang rad was quite large and i started cutting based on that. Haste makes Waste ....

You'll see the tabs there, I was planning to fold back the sheet metal to make some affixed points exactly where the rad grille will join at ...
This next shot shows how much of the stock fresh air ducting I ended up cutting away. Without any real idea how I'd fit the rad, I sliced into the fresh air boxes, which i will close off as a smaller compartment to make them useful again. I then ended up slicing into the bumper support for the rad instead of cutting upwards ..... oh well ... I have a compelte spare nose in the back just in case I foobar something up completely LOL
Here's another noseshot of the rad installed. I plan to move the overflow bottle to the right or left of the rad, not sure on gas pedal space at this point.
This allows the rad cap to be accessed from the outside from behind the rad grille, so I will enclose the interior by the looks of it too and not need to have access from there ...
The rad sits nice and high and little is cut off from air flow in this position. My other idea was to cut up into the frash air grille and let the rad cap poke into the fresh air grille betweent he 2 air flaps, that would be much better for air flow and kinda cool ..
So, it moves forward at a snails pace, i hope to have the van kinda invading the whole garage shortly across both bays so i can start to gut some of the interior and stuff. While the vehicle is apart in this state, I will get the body media blasted underneath and fix up any bad areas before they get too bad .....
