Flex-A-Lite fan measurement needed

I need the measurement from the back of the fan blade retaining collar to the timing cover.

Let me know what radiator you have too.

Wondering if the measurement is different for stock vs aluminum radiators.

I'm designing an auxiliary alternator bracket and trying to see if there is measurement differences between each radiator brand. The fans mount to the radiator, not the cab.

Thanks!

I'll start:
1)
LMR "SVE" aluminum
Dual core
6 5/8"

2)
Mishimoto aluminum
dual core
7"

4X4!!!, E85, Whipple 3.4, Monster inlet, 5" CAI, Custom midplate & spacer, Crusher Whipple TB, VMP3500, ported TFS heads with oversize valves, custom cams, GT supercar valvetrain, Manley H-beam rods, Diamond pistons, 465 pumps, Fore regulator, ID1300 injectors, built 4R100 , blower slut valve body, 2400 PI converter, superduty trans cooler, 3:55 gears, OBX longtube headers, Full 3" exhaust, superduty T.C., custom driveshafts, coilover conversion, custom drop knuckles & lower control arms

What is the measurement to the end of the collar?

I got 7 3/8" from the end of the shaft to the timing chain cover. Stock radiator and Flex-a-Lite 270 fans. The collar was 1/4" deep on the shaft.

I'm not completely useless, I can be used as a bad example.

Thanks guys!! Looks like aftermarket radiators are 3/4" closer to the engine vs stock.

I'll design the bracket based off my truck. Seems it is worst case scenario.
