Plan B, just happened to look at my 149. I thought it had 23X8.5-12 tires on a 12X7 rim's it but it has 23X10.5-12 tires on a 12X8.5 rim's so what I'm going to do is replace the bolts on the 149 with 3" long studs then I can use my spacers and the JD wheels on the 149 and put the wheels from the 149 on the 1641. The bolts are a PITA anyway so 2 problems solved for cheap money. McMaster has the studs and lug nuts with very good prices.
