Hey ambros I was looking up some of the rods for sale on ebay and omnimodels has a duratax rod that look very close to the grp I know the materials may not be as good but for the price I think is worth triying it, the lenght of it is 37.5mm from top to bottom and 30mm from center of the holes the only problem with it is that does not say the size of the holes I will soon take my engine apart to measure the lenght of my rod an if it is the same I will ask omnimodels for the size of the holes,this may be a cheaper way to go even if it will have to be replace sooner. This rod is only 13.0 dollars shipped
