I don't mean to be smart here cause I am in New Zealand and I know of one being wrecked down South, in Invercargill. If you want, I can enquire about whether or not its still got a rr..... oh no, sorry, Its a pivot steer job.
I also am on the hunt for bits for our Hough 65C for our ole beast. Love dem old girls that don't need a wizz kid to sort the computer type stuff. I have all the manuals for this one and so far, I've managed to do all needed repairs (which luckily, were few)
Good luck to thee and also.... Seasons Best Wishes to thee, she an dem.
