1966 Valiant rear quarter patch panel question

I just recently bought the right rear 3/4 panel for my 66 Barracuda from Laysons. It looks very good to me.....the only issue is that he the trunk extension is short of reaching the bottom edge by about an inch, as I believe it is intended for 64/65. This fact was told to me when I bought it, I opt'd to weld a piece in (as suggested by the sales guy). While I haven't welded it it yet...no bad experiences here.

This work is really not for beginners. YouTube guys can give you the false confidence to take these things on, making all the right moves at the right time. Unless you're welding these things a few times a week...you might want to get someone that does and save yourself a headache.
I think Laysons is the only game in town for these. Possibly the small patch panel, 64/65 can work for you if your damage is on the bottom.
