Yep. The best 2 are the top bellhousing bolts. Inverted Torx. Spent a couple of hours on my 88 Jeep getting those out. Also the 13mm 12 point front hub bolts. They work out awesome up here in the salt belt. You get one shot at them. Hammer on the socket and dont take it off till the bolt breaks free. If you take off the socket all the rust falls off the bolt head, socket rounds off bolt. Now you cut off the bolt head to get the hub out then find out the parts dept doesnt stock new bolts. Man I've been in this trade too long. LOL.
