No Stiffy has it wrong....

A cool garage, a slab of beer or bourbon substitute, a comfortable chair and a mate to do all the work!!

Then it's a piece of cake.....for you!!

But seriously if the RMC is the same as the G-Force you may be able to manipulate the radiator out the top.

Means removing bonnet hinges and so forth from above the front top cross member and provided there is enough room for the radiator to lay back off the front of the bottom rails and the lower radiator brackets ( may have to unbolt these off the chassis).

Hopefully someone with an RMC and this experience will now chime in with the real answer.

Best of luck.

Still think my first option is your best bet!
