Default Mk2 2.4 fan belt

Can anyone give me the correct fan belt size for a 1960 MK2 2.4 manual car.
It is the early single V belt system with A size pulleys.
I have researched all of my workshop and parts manuals unfortunately they are mostly for 3.4 & 3.8
The shorter 2.4 block and lower generator mounting needs a smaller belt than the 3.4/3.8.

I'm sure you already know, but tie a medium thick rope around the pulleys tightly, mark it where both ends meet, deduct 1/4" inch, and measure the diameter.
Small V belts are used in zero-turn lawnmowers.

Also I did a search and 2.4 belts appear to be available in many sites in UK and US.
Rock Auto.com, Lbcarco.com in the US list belt for 2.4.

Attached is the current state of the MK2 2.4 in bits.
The fan belt that was on it was too short and at the limits of adjustment (or beyond!)
I simply need the size/length as V belts are readily available locally.
And another thing is the sheer transport cost of getting stuff from the USA and GB. Bloody unbelievable!!
I guess I will have to get the engine back together and measure it myself.
Pulling it apart to replace primary(lower) timing chain

shipping anything, even the smallest package overseas, or to Canada from US, or even US to US addresses, has become absurd. I have given up going to the post office or UPS.

Bill, If your fan belt part is # C13593, I found that Gates makes a belt that their website says is a fit: Dimensions : 925mm by 10 mm. if that is not your part, let me know what your part number is and maybe I can find one that shows the dimensions.
Cheers !

Depending on the engine number there are two fan belts for the 2.4 engine as there are also two for the 3.8 / 3.4.
Below are the pages from the parts book showing the engine numbers relating to the part numbers.There are no dimensions in the parts book.

2.4 engine part numbers.



3.8 / 3.4 engine part numbers.




Schematic diagram of the fan belt which is the same diagram used for the 2.4 and 3.4 / 3.8

Thank y'all
The engine number is BG 5519-8.
That part number C14723/2 would be the correct part.
The fan belt which was on it was a Gates 915 and I had to undo the adjustment bar completely and push the generator right in against the block and even then, it was a struggle to get the belt off
That 925 mm sounds closer to the mark.
