Large frame powering steering boot

Hi guy,does anyone know if any other manufactor used the same cylinder thats used on the HT-tractors for the power steering,as most of you know once the rubber boot cracks and breaks there doesn't seem to be anyone that has them,not even Sonny's or Samsbolens, I have the chance to have exact reproductions made,would look like the factory boot,,of course there is the usual tool set up,if I can't find any NOS ones I may persue having this done,still waiting for exact cost,I do know I have to buy 100 of them,how many guys would be intereted if I can put this together,I know cost means alot,as it does to me also,just trying to see how far to go with this,once the boot cracks and breaks it can lead to major problems down the line,I'm guessing from talking to them looking at around $50.00 ea,but maybe less,let me know what you think, Thanks, Rick
