Changing the fan shroud: what else?

[WM23N1G1]

Hi,

on my Bee, the fan shroud and fan are shot.

As I saw this thread, I said to myself: perfect!
Bill Allphin confirmed his fan shroud is made to fit on my #3443962 radiator. The problem is the radiator is a simple core, with a little one in front for the engine oil:

The car left the factory with a 383 and a A833 (unknow rear axle). It now sports a souped up 440 and a 3.91 741. The temperature gauge never worked, so I never worried about the temperature
 
(except it was hot as hell in this car), but... reading the original shop manual now make me want to get things work as they should.

In a few weeks, I'll get a 3.73, but I don't think it will change much. I'll get a new temperature gauge, and a fan for sure.

Do you think I should :
- get a new fan shroud, fan, and temperature gauge
- get a new fan shroud, fan, and temperature gauge, and get the radiator be re-cored with one more row
- change everything to put a 26'' radiator.

I thought everything was welded, but there are lots of bolts:


Is it something easy, or a pain in the neck?

Hi,

took a decision: I will use a new fan shroud, new temp sending unit, and new viscous fan package.
If I still have money, I will get my 22'' recored, with 2 more rows.
