I fitted one of Simons rads to my plus 8 back in August/September.
After removing the Grill and Steering Rack the old one came out from below. (Good opportunity to check/clean/adjust the rack if necessary)
Radiator fit is very good and accessibility is not bad either, again it goes in from below.
Had to modify the bottom hose to make it fit but that could have just been my car.
Highly recommended.
