Have a setup on my car now that held a screwdriver antenna uses a 3/8-24 stud mount. no longer doing HF from the car want to mount a 2/440 whip with a 3/8-24   threaded end.  I have looked everywhere ,only found 1 such antenna a mfj-1414. There must be some other vevdors out there,anyone able to steer me in the right direction?

I have found no 3/8"x24 thread multi-band antennas in my own searches.  

Lakeview Antennas does have several single band units that could be mounted on quick-disconnects for band changing.  Download their catalog in PDF format.

Hustler antennas has one choice, also single band:

Another possibility is to use a multi-band antenna that has a PL-259 connector.  Use this adaptor from MFJ to go from 3/8"x24 to an SO-239 (it appears on page 70 of their printed catalog):

I’m using Hustler’s models CG-144 & SF-2

While neither of these are made for 440, I've used them both and they do work. That means I've been able to talk through repeaters and be heard. Since 440 is close to a 3X harmonic of 2M the match should not be too bad.

I’d start with the SF-2, the CG-144 is a collinear which means who knows what type of pattern I’m putting out. I wanted a QD mount, and they are 3/8 stud. All I could find were the Hustlers. I started with the CG-144 not realizing it was 7’ long, it does not stow too easily. The SF-2 is much shorter. I can take it off and leave it in the car.

For $18 + shipping, the SF-2 is not a major investment and works excellent on 2M, and it might give you want you need on 440.

If you put a Hustler mast on the mount and then put a plate for holding multiple resonators you can get 6/2/440 and one other band off the same antenna if the marketing materials are to be believed.

I've not tried it but thought about it as a what the heck type thing.

Look at item Y about 3/4 down the page.  Hard to beat for $10.
