I need to replace window pack
based on dacor parts manual I need part 82954 ( or 12470) which at appliance pros.com is part # AP3395046 and sells for $203

there is another dacor window packet listed at appliance pro - part AP3395638 which also seems to be a window packet for dacor and sells for only $128

obviously I would prefer to buy the chepaer one if it will fit into my oven. The sales rep at appliance pro could not verify that the second and cheaper part would fit. WHen she pulled up my dacor oven she got the first and more expensive part listed. Can anyone tell me teh difference between these two parts and whether the second one would fit ?

Thank you
Michael
