I checked Ford/New Holland online parts, and have it priced @ $110.00, but not real clear if it is still available. Next best thing may be, to check salvage yards, and look for good used ones. I would have to guess they would want half the price of new for the complete assy. however, they may just sell the part you need.
Here is a list of 63, Ford 2000's in salvage yards, but not all 3 cyl. models.

I came across a thread from another forum, where a fellow was converting his to one off a 3600 or 4600. Those according to the parts description are 12.75" long, and should put them up to the top of the trans. case, instead of having to reach down to the other one on the foot board. I may have to check into one of those myself..!! P/N for the long one is D6NN2824B. You'll need to get the bracket to hold the top, #52A in the exploded view, following this link.

I went back to Tractor House, and looked up 3600 & 4600's. What 3600's that have a pic of the right side, blowing the picture up, show having the long parking brake handle.

From what I can see, a few of the 4600's have the long one too.
