1988 Chevrolet 454 Dipstick

[87k5]

I need a dipstick for a 1988 Chevrolet 454. I am looking for a stock replacment. GM has discontinued the part, and my searches on ebay don't return what I am looking for.

I don't want billet / chrome

Mine (the one I need to replace) is in 3 pieces:
Lower tube
Upper tube
The dipstick itself.

Thanks,

Charles.
