I have not had a lot of time driving the jeep since it has been done but the hy-spools much better than the stock bread truck H1C/16. The reason I was thinking of putting on the IIps62/12 is that for that reason the stock H1C is a 16cm and the HY-35 is a 9cm than the 12cm should be a pretty good compromise between the two but I must be missing something
