Bethany Housewares Probe Control Fits Heritage Grills No. 730, & 735 1-3/8 Inches Spacing

my 730 model lefsa grill was my Grandmothers and it is about 25-30 yrs old. Do you think this cord will fit? Many negative reviews.

I am looking for a pc057 probe control for a society 7253 electric skillet regal ware. do you know where i could find this part?

How long is this cord? I have a couple cords but they are so short.

how can i get a heat probe for bethany grill 215?
