[k zen]

Hi everybody

I am looking for the distance between center to center of the holes in the block , i bought the scroll attachement but i want to do the block myself , they sell the block for 108,00$ at unibender , just imagine a piece of 2x3 and 3 sleeve of 3 inches , i can do that for cheaper i think .

Sorry for the small pictures .

THANK YOU

Bobby
