Driveshaft issue?

[Badeddie]

I have an 87 Eddie Bauer BII. I'm getting ready to replace the rear driveshaft. I crawl under to have a peek to see what wrench or socket I will need and those bolts look like something you would see in an aliens starship! Could someone please tell me what size and type bolt this is so I can replace the shaft? Any help would be appreciated because my Bronc has been sitting two months and I'm dying to get it back on the road. THANKS!

I have a 87 as well them bolts should should take a 12 point wrench or socket they will be pretty tight a closed end 12 point wrench should work best sockets don't fit well around the u-joint area don't forget that they are metric size 14 I think I can't remember 100%
