37/47 transposing gear on 9”model A


I need to cut some 25 tpi threads on my south bend 9A qc lathe. I purchased a printed 37/47 transposing gear of eBay thinking it might work. I can’t seem to find any information on how and where to install the gear set on my lathe and how to cut the threads I need. Any pictures or advice would be great.
