The ordeal is finally over and I have my parts. The second center grill fit like a glove and looks great. They made a great effort in getting me the correct parts sent to me in a timely fashion...
Unfortunately...The second lower grill they sent me was exactly the same as the first and was waaaayyyy too wide to even fit. Another problem was that the hardware was not included in the second shipments...I had already returned all the hardware that went with the 2 pieces that I sent back (like the vendor told me to do I might add). Luckily I am handy with a grinder and happened to have a set of 8/32" nylocs and some fender washers that worked out well. I had to grind off about 1/4" on each side to get the lower into place and it was still too wide. I had to give it a little bend to get it in and now it bows out just a little. No one but me will notice, but I'm the one who matters most...
Overall I am displeased with this purchase and wish I had not done it. The final result is satisfactory. It looks pretty good, but I am not happy that the lower piece still does not fit perfectly. I probably should not have taken the grinder to the lower, but I did it out of frustration and not wanting to wait another week or more for them. I think that E&G just made the part wrong. All this and the fact that they did not include the hardware with the parts...
Here's a pic in the dark. I will take some more in daylight conditions. Also, I forgot about getting the measurement...Oh well...
