Anyone know where I could get the correct one?

I have the double sump 351W oilpan with the thread in type port on the side of the pan for the dipstick.
Moroso oil dipstick is 1/4" NPT but the pan is different thread.

Help please....
Thanks

The 351w duel sump pan was most often used on '79-'91 Crown Vic police cars. That would be the easiest place find one in a junk yard. All the venders sell them as 351 conversion parts. They measure 19 3/4" from the edge of the cup that goes over the tube to the tip of the stick.

Looking for dipstick and tube for this oilpan.
Running into dead ends trying to find a cheaper replacement.

That lokar dipstick is nice but with shipping costs I may as well buy another 351w oilpan set.

The same answer just find a '79-'91 Crown Vic police car in the junk yard. The tube is held in with a 5/8'' nut like 3/8" steel tubing compression fittings, in the side of the pan and a bracket to one of the exhaust manifold bolts. It may cost $5 at a you pull it. How cheap do you want it? I don't think cheesy chrome plated after market parts are compatible. If there are any, they would be made for '80s fox body Mustangs.

Yards in Hawaii are in short supply of older vehicles plus they will probably charge me $10. if I did find it. Slip in type are $12-$14. listed and in stock. I need a thread in type.
Moroso aftermarket dipstick I got is 1/4" NPT and does not fit. I could madgyver it but for now looking for answers here on thread size.

I believe the hole is 5/8x18 straight thread pitch. It's standard nut to tighten a 3/8" tube with a flare or double flare fitting. Ebey has the dip stick and tube with tab to the exhaust manifold bolt for about $8.50 delivered from several venders. The 5/8 nut is an Ace Hardware piece.
