Crankshaft pulley

I ordered a 4.8 serpentine pulley for my engine which turns out to be the wrong one. The issue I have is that I do not know what I need!
Well I know I am using the intermediate timing cover on my 4.6 Gems engine and I am using a serpentine drive. But this seems to be insufficient in which to order the part.
They are asking for part numbers. Bearing in mind that I need the entire crank pulley assembly what else do I need, damper, etc.
Cheers,
Adam.

They should know! Tell them its the first engine to have a serp belt, a 3.9. All the 3.9's that had serp belts are the same. Rimmerbros?
If you can use a lathe you could make a pulley to bolt onto a standard damper.
Edited to say the complete bottom pulley is made up of three parts, the damper, a balance ring (goes on the back of the damper) and the front serp belt pulley which goes on the front.

You'll need a crank damper and the correct pulley to attach to it. Both probably from an intermediate engine although as you have a long nose crank I'm not 100% sure. The intermediate had a short nose with long keyway so I think you would need a spacer.
John Eales advertises a crank damper on his site which may or may not be cheaper than a Rimmer Bros part.
The intermediate pulley has a bigger offset than the later dissyless version.
You can see it all on Mez's site.

Thanks Mike,
I have the long nose crank yes with intermediate cover and therefore do indeed have the spacer, I have the thrus washer and bolt, just need the right pulley.
My problem is that I am ordering from a box shifter and they want part numbers, no good sending photos or describing.

I see.
Might be better to start with the LR/RR models that had the intermediate engine which I think one was the '93 3.9 Disco but again I'm not 100% on this.
What are the odds on an intermediate damper/pulley being 3x the price of any other I wonder? Hope not as I will need soon one too!
