Product review (4 stars): Works OK to replace Norton model 501A or 7432P131
I had to remove the ignitor from the metal holder (did not fit my oven bracket) and had to remove the plug and used the wire nuts and it works just fine.  If everything had fit just right without these modifications I would have given it 5 stars.  Anyway, it's a bargain - they want a lot more money for the same part at local suppliers as well as other websites.
