Welcome to the forum!
If you would like to request a part for you machine, you need to run an ad in our "Wanted" section. You can find it
here, in the Trading Post section. Please make sure to follow all rules.
As far as the pump goes, yes it will fit into a 129 as all hydros for the IH machines were the same except for that some are ported and some not. However, I am doubting that you have a ported pump on your 107 if it has electric lift unless it has already been swapped. If it has, then it should have had the pressure relief spring changed or removed, as you cannot just cap the ports and not use them. Hydraulics don't work like that. Point is, if it is capped off, it may be missing other necessary parts, or may have already damaged that pump. Hydraulic lift was not an option on the 107 and should never have had a ported pump. Perhaps you can post a pic of the pump so we could verify.
