Since my block is an 83, it has a little plug where the IHI coolant return would go. Im trying to get that bugger out and am having no luck. Ive tried the closest fit in my allen set, but the wrench turns while the plug doesnt. You know what that means! So I stopped before it rounded out. What size is this thing? My set is a complete set of allen wrenches, but the plug must be a screwy size...

87 Ranger 2.3T 5spd
(2) 88 Ranger GT 2.9 5spd
86 Daytona Turbo Z 2.2T auto trans
88 TC 5spd~money pit
88 TC 5spd~78K miles
