I see you list a lot of water pumps...with images that look identical ?

My problem.

I run an LS1, Camaro style accessories. I run a dedicated blower drive out front and this does rub slightly on the large bell shaped water pump pulley.

I need to retain the Camaro accessory belt position, but I need a shorter water pump pulley. The original is stupidly long and bell shaped for no good reason ?

Thermostat location and heater hose locations would ideally be in same or similar positions. I am flexible with top hose location.

What are my options ?

LS2 short pulley....I do not have room to space the entire pump out by the required 20mm as this will foul my blower bracket.
Vette, C6, LS3,7 ?? what's the difference ?

Evans pumps...unsure which model, although I dont fancy having to use a dedicated non water coolant.

Edelbrock ?

Or this ?

my problem area, circled in red. Best i can measure, outside edge of my accessory belt runs 120mm from the block face, ie 4.72"
I dont need a huge amount more clearance, even if the pulley was pressed in a further 3/8" to 1/2" it would be ample. But a shorter more square pulley can only be a good thing.
