Mystery bolt size
Hey all,
I'm doing some spring/quarantine maintenance on my '84 GSL-SE and have run into a road block. I'm trying to change the transmission oil to some new 80w-90 but I can not figure out what the size of the bolt head is on the drain plug. The largest socket I have is 21mm and it isn't big enough. I tried using an adjustable wrench but the angle is weird and the bolt started to strip. I've already stripped one bolt this month, trying not to have such an enjoyable experience again lol. Does anybody know what size this bolt is? I've attached a photo of the bolt in question.
Thanks
