Gah!! I'm so upset! I got the part this morning and it doesn't fit in there right! I have emailed the company I bought it from, because it says on the bottom of the invoice it says, "If the item has installation/fitment issues - Please contact me and I will do my best to assist you. The replacement parts for vintage machines often require a special approach to install, and may not always look exactly like the original". Of course, she is on vacation until Tuesday, so maybe next week, I'll be quilting again.
