There is some space inside the hub so a slightly longer bolt is not a problem. I'd buy 32-35mm bolts, test fit them and then slowly rotate the wheel, if it rotates without the bolt touching anything inside the hub then you are fine. IIRC there is more space inside the rear hub than the front so make sure you test fit both front and rear.
Also if you have access to car scrap yard then 155, 164 and GTV's all have longer bolts than the 156 so might be a cheap option to buy a set of those, at least for test fit
At all costs, obviously you must avoid too short a bolt, 10mm of bolt thread into the hub itself is required
