Ebay sellers have a full aluminum radiator for an early model mini cooper. I have used 2 of them on diesel conversions and they work and cool fine. They are about 11 inches wide and 15 inches tall and about 1 1/2 inches thick. I think I paid $55.00 with free shipping.

THANKS for that info!  I have room for 13" wide and over 17" tall, so that will work just great!

Been mocking things up today.  I will need to raise the hood & dash about 1 to 1 & 1/2", and do some minor angled cutting above the axle pivot housing to give oil pan clearance.  I have to machine a flywheel adaptor for the pulley that drives the hydro belts before I can weld in engine mounts.  The same pulley is where the rear PTO shaft bolts to.  The radiator takes up all the room where the battery originally was located, but I "think" I can make room for a GT size battery beside the engine inside the frame rails.  

  It will be fairly involved, but to me, it'll be worth the effort.  It took me 5 years to finally finish Hogzilla, and may be quite some time for this project.  I'll hack at it when I find time.  

  The hood actually closes in factory position, but not enough room left for air filter hose which comes out the top side of the valve cover.

Just ordered a Mini-Cooper radiator, 10" electric fan, and a fan thermal switch for this project.  Figured best to get all needed parts stockpiled so I can fab what's needed as time allows.

Can't wait to see the look on your face when this one runs under her own power. Bet it beats the one from the HD12!

Radiator and fan arrived today!  Gonna be quite a while before I can really get into this project, so these go on a shelf till then.  I have a thermal switch I'll either mount at the engine, or drill/tap the drain cap & install in this radiator.

Flea market find for the 720 today....new seat for her.  I'll store all these parts away and be ready this fall or winter when I really get to dive into this project.

Just been too busy at work and home with hay & such to do any tinkering, but this project is on my mind a lot still.  Hoping for this hot weather to break so I can get some time in  on it.  My next thing to do is to take the old drive coupling off the flywheel so I can machine it to fit the OE belt pulley to drive the tranny belts and PTO shaft.  Once that is done, then I can get the engine mounts built & really get into things.

Hope all is going well with the project. I'm doing the same thing with a 20 hp yanmar. She fired last week. Hope to be driving in the next couple weeks

Boy ,that turned out very nicely. Between you and Daniel, I'm thinking I need to pull the Onan out of my 4140SIM and drop one of my diesels in it.

What are you doing about using the rear PTO? Did you use the OEM setup and power it the way it was from the factory?
