Just the stock mount, haven't had any problems with them. max load I carried was 20 kg of potatoes in the 1392, handling was a bit questionable, but the basket held up just fine. I'd recommend to switch out the stock nuts with lock nuts though as I've had them come loose a couple times.
I have 1372s on two of my bikes. One of them is fitted with the struts to the dropout eyelets and the other one is attached to the lowrider braze-ons. The latter set-up feels significantly stiffer but it might also be due to the thicker forkblades and ahead stem on that bike.
