I highly recommend totake measurements and pics when doing these panel replacements. it starts out as a simple thing but then you start cutting and removing rusty stuff and when you're done that and have found solid steel to weld to you find you have lost the reference points to get the new part installed so everything fits like it should. make some marks on some tape out of range of the repair and do some dimensional pics or run some lines acriss between points on both sides of the repair spot so you know the lines should line up when thngs are correct.
just a thought. been there before
