Gees, thanks so much, when you confirmed the sae #3 bellhousing that really helped me, there are some of them out there with passanger side starter and tabs like yours, I been looking at one of in a yard down here for a while, how much are the flywheel and pto hub with the stock clutch set up, do you have any motor mounts for sale as well, I have wondered if one could add more discs to the pto if it every became a prob with too much hp, I wontburn up the tractor with overloading it and understand i will not have a governed engine in it but can live with it, was just going to install the 12 valve out of a dodge in it and maybe remove the turbo depending on how much i feel the tractor can take, wonder what the differences in the pto clutch stak #'s discs in the housing, bull gears and transmission is between the 2 tractors 1750 vs 1850?? I have that clutch housing out of a 1850 to use but never did go get the tub for the 1850 perkins that is wrecked down here in a yard, never did like the idea of torching a Oliver in any waylol We used to have 3 dealers down here but they have been gone for 35 years now, such a loss too, they were all good dealerships, thanks again for the info, really liked your website with all of the photos
