The HPS70 is listed with 2 codes;
05243 With 2-1/4" cylinder
05253 With 2-3/4" cylinder
The cylinder is the assist cyl. that goes from the pitman arm to a bracket on the frame,btw.
Larger cyl. is usually used with a 9000# & up front axle.
Since you have a CO the gear may not be exactly the same externally as one used on a conventional cab. Check it in your MT-112. If so that may make finding an exchange unit difficult.
Internally they should be the same.
Didn't find much in the way of parts for that model gear,Midwest lists the valve and 2 seal kits,all
That's about it.

Never argue with a fool...
If you don't have anything nice to say...say nothing.
If you don't learn something new everyday...you weren't paying attention.
THINK! Be sure brain is connected before mouth is in gear.
