Has anyone installed an after market cruise onto their old ride? The last one I did was a Sears unit where one glued a magnet to the drive shaft. It seems Rostra is the one most touted now and wondering how difficult the install is. Ididit has one for $225 which is the lowest price I've found and one now has to choose between one with an electric speedo or cable driven. The old right knee locks up if left in one position for an extended time so cruise control is now on the calendar. I'll let the moderator decide if this is General, Electrical, or Drive Line, qualifies for all.
