Default C4 hardtop removal issue

My 1989 vert. has the OEM hardtop installed.I dont have the factory provided ratchet wrench to remove the rear mount hold down bolt-one on each side.There is very little clearance to get at the bolt.
What is the proper size wrench,and are there any originals available.The factory original was a flat ratchet wrench according to my shop manual.
Will appreciate any helpful info.

T 40 torx is what you need. Repos are available many places on linee for about $30 or so.

My issue is not the t40 torx for the front bolts-but the rear 2 hold down bolts.
