[QUOTE="TimberTim, post: 436944, member: 20208"] No it's not hard at all .yes the discs, on my "91" the large ones were 2'' AND THE SMALL ONES under the Exhaust Manifold Gasket on the Head were 3/4" . Drain coolant and simply drive a flat screw driver thru the Brass freeze Plug and pry out old plug. Clean the block opening with a wire wheel and sand paper until shinny . Put a light film of RTV Sealant on the edge of the freeze plug ( this will seal any imperfection and act as a lube for installing). Gently tap the plug with a hammer until starts and it stays in the hole by its self. then place a piece of flat stock over the plug that covers all edges of the plug, our use a large socket ( upside down) that covers the whole plug and gently tap, tap, tap, the plug into the whole, Don't Bam, Bam, Bam, the plug. set plug depth to just a hair below the chamfer on the block. this should cost around $20 Bucks....Tim [/QUOTE]
