Check my post from yesterday in the General Topics forum about Springer top tree. Throttle Masters on eBay has them. It’s 100.00 and let’s you convert to the bars you’re looking at. More than likely you’re going to need all your cables replaced with longer ones and and wire extensions. Make sure the bars are dimpled. If you’re doing the swap yourself this way expect to spend upwards of 500.00 for parts depending on the cables you buy. G.
