@Marshall. If you have your current sender, you can quickly get the details for what you will need to buy. Senders have part number markings/ temperature ranges stamped along their hex faces.
ref Picture. Manufacturer/Numbers / temp/ volt range part number written in pencil are stamped along each of the hex faces. ( you may need a magnifier glass... or take a pic and blow it up on your screen).
Then- find your sender Part number in the VDO catalog ( jump to page 56-57-58): https://www.vdo.co.uk/media/74...ogue_2019_lowres.pdf
...And. shop away... you can find these anywhere- any VW online shop, Amazon. or your local auto supply stores like NAPA.

Sample of a few common VW senders with details for your info:
—from left to right: 1, 2, 3 described below.
1- On the left is the VDO sender 300f, M10 x 1 thread, 22mm long.
2- In the center is the OEM VW German made sender of the the same M10 x 1 thread, short 10mm, 150c/300F. VW OEM part number #1H0 919 563 - oil temp sender, 0-150c range, used on 70s to late 90s VW cars. Also Audi cars.
They both ( 1 and 2) have the same 10-180 Ohm range... The OEM VW short one can replace the M10 thread sender for the aftermarket VDO oil temp gauge with 150c/300f range. The short sender will not protrude into the oil passage like the longer VDO unit. The longer VDO unit can trigger the oil pressure sender.
3 - To the right is the more common and cheaper OEM VW sender part #049 919 501 - oil temp sender, short 10mm, 0-120c range also used for mid-70s to mid-90s VW stuff. And commonly used now for small aircooled engines. I have the VDO version of this one installed in the car, part number 323-088.
hope this helps.
