bell house to trans bolt head size?

[donlightbody]

Anyone offhand know the size of the bolt head (to get a socket on) 88 BII mitz 5speed? the bolts are loose and there's quite a gap now. I found yeaterday that with the right extensions and u-joints I can get a socket on the bottom 2 through the inspection hole but having hard time getting the socket set on the head, think I just need to know the right size. no garage ,snow and cold, I don't want to pull the trans till summer if I can get away with it. Thanks all.

Yup, they should be a 13mm head bolt. At least the last time I played they were.
