Oh, and to your grave digging question about the 400ex shock, it fits Both, kinda. The rear will bolt right up to the blaster rear with a set of bushings you'll need. For sale at KEN Oconner racing. 25 bucks! And it's one of the best mods you can do suspension wise on a blaster. The fronts off a 400ex will fit also BUT, you'll need a shock relocation kit from diamond j or +3 long travel a arms from ASR. Reason being, they're an 1 3/4 Longer than a stock blaster shock. Hope this helps! Search 'Cheap Shocks' and u will get some more info.
