Dave - well according to the on-line CCC Parts List Item #19 is Part No. 473922-R1 but I think they are being sneaky and dropping the " IH- " prefix from the listing.Yes, I did notice that!! Ha Ha!
Are you sure that's the right part number?
I thought it was IH-473922-R1
19 BRACE, EXTENSION | 1961 TO 1967
So, just to check on them, I also looked it up in my handy dandy CPE-2 PARTS CATALOG (issued 5-'85) and it actually shows the same Part No. without the IH. So I had a scan look at all the other Part Numbers listed in the CPE-2 and NONE of them have the IH prefix. There's an IH emblem with the circled R on the front cover of the CPE-2 catalog but we know that by 5-'85 when it was updated, that IH no longer owned Cub Cadet. CCC had the rights for a period of time to use the IH emblem. So I don't know if IH dropped the IH prefix, or if CCC dropped the IH prefix.
