Why didnt you just find a Blaster pipe and put on it? I think if you had used a GP760 pipe you could of used the stock waterbox. Not sure.
I have a 62T/64u in my blaster also, its a huge difference.
I dont have those parts laying around in my parts bin. I also dont have the money to buy a blaster specific pipe, ( i would if i could). I never had a any blaster specific waterbox, (mine never came with one).
mind you i got a whole donor raider for only $100, that had a seized pump with a 62t that needed nothing and ran perfect,.
But u can sponser me and send me parts!!!!:439:
also isnt the bolt pattern from the head on a blaster 61x/62t different from a raider 62t, so even if i did have a stock blaster pipe i couldnt use it. but i guess a aftermarket pipe would have worked, but like i said$$$$$
