Yeah, but the Berg unit won't drive a gauge. It's basically a temp switch that closes at 230 degrees F to make your temp light in the dash come on to tell you to either stop or slow down to cool the engine down (I think it starts to blink at 225 or so) - a whole different basket of snakes.

VDO made a gauge-based temp sending unit that took the place of the dipstick on 356's and some VW's (I believe it was a post-factory add-on), but they're hard to find these days. I'm also unsure as to the resistance range of those senders versus either stock or Brazilian/Taiwanese reproduction gauges. In other words, a stock VDO dipstick sender may not adequately drive a reproduction gauge - I just don't know for sure.

Good luck with your source.

A few (very few) guys were running them back in my "chasing the racing guys" days in the 60's - 70's, but pretty much everybody was running the sender that screws into the block next to the distributor.

Theoretically, the dip stick unit might give you slightly more accurate readings, but then you're subject to the accuracy of the sender itself, and they're typically all over the place. Besides, are you really going to notice a couple of degrees difference??

What a bunch of us have done is to use the standard VDO sender (next to the distributor), along with the Brazilian reproduction dash multi-gauge. That gauge typically has no numbers on it, just a colored band. Then, we get a dip-stick thermometer from:

mainelycustombydesign.com

for about $50 and use THAT to calibrate the dash gauge (I just drew a line at 180 F and 225F as my operating range).

Works fine, is easier to find than the sender you're looking for, and with care it can be accurate to within a couple of degrees or so.
