A great upgrade for the 8.8 is the C clip eliminaters. They'll give you piece of mind just knowing your not going to spit an axle out the side.
I'll throw some pics of my buildup soon. It's a 85GT mini tubbed, skinnykid cage, 3/16" boxed torgue boxes, through floor frames with waterfall tie ins, tubular front K etc. 540" big block with PA SuperComp C4 TB. Lots of small body mods that only Mustang fans would notice. Engine is at the dyno shop now and I should have it ready to go in a couple weeks. Getting anxious.
