Does anyone have the dimensions and thread count for the differential fill plug? I am looking for the brass one and am trying to get it off of Amazon Prime but can't find it.

 

Get them from here:
FILL PLUG RADIATOR TDI V8 1989 ON BRASS, PLC997, ERR4686 - Rovers North - Classic Land Rover Parts
$3.79 each. Pretty inexpensive.

 

I saw those but was trying to get them through Amazon Prime with the two day shipping because right now I am driving around with bent ones.

 

1/2 bspt

 

So that is the same as a M20 plug?

 

I have no idea.

 

Don't go too deep, don't want to grind it on the crown gear

 

No. Not metric. British Standard Pipe.

Not common in the US and it's not that same as NPT.

I saw a conversion chart that said a 1/2 bspt is the same as a M20.

If you would of ordered this last night with the link it most likely would have shipped today..and be to you by the weekend or sooner. You could always reach out to ZGPhoto who works for RoversNorth and get an estimated ship time.
