That is the biggest problem. I ordered especially Maverick Strada XT Universal drive shafts and they had 115 mm which was not enough. So I sent message to the eshop, that there are short and I dont know what to do with them. They measured another package and found out, that also the others for Strada XT have only 115mm which is propably the lenght of Universal Drive Shafts for MT. I couldnt find anywhere on the whole internet, what the lenght should be. I wrote message to the other 2 eshops on ebay and both wrote me back, that Universal Drive Shafts for Maverick Strada XT have only 115mm.
The original package dogbones (cheap ones) have estimated 127mm....
