Sounds good.
Some comments on the grilles:
The ones you linked to are for the AR2ax and will NOT fit the AR2a.
You might try emailing that ebay seller (vintage AR) and ask if he will sell you AR2a grille boards (without the cloth). Then you could cover them with the grille cloth of your choice.
Or ask him for complete AR2a grilles. They are consistent with the original appearance, but not all 2a's had the natural linen grilles. Here's a shot of mine, with funky original 60s grille cloth.
If you decide to make your own, you could use thin (1/8") Masonite. I can give you the measurements. On the 2a, the grilles are the same width as the opening in the frame, but they are longer than the length of the opening. You bow them and slip the top and bottom into the slots behind that front frame.

I mailed him a little while back and he said he could send me the AR-2A full grill setup with cloth and logos but after considering a different color, I mailed him asking him what he would charge for just the grills and logo's with no cloth. I hope to hear from him soon. Hopefully it will be a bit cheaper without the cloth. By the way, those are some good looking AR's you linked there :D

By the way, what is negative and what is positive in the rear of the cab? There is the 1, 2, and T posts. The 2, and T posts are tied together. I think I have it hooked up as the T, 2 as positive and the 1 as negative. Is this right?

Finally got my AR's covered today. I cut the frames and my lady cut and mounted the cloth to the frames. All I need left is to order the emblems for the grills then they will be finished. By the way, the fabric I used was an 18ct Lambswool that is colored a slight off white with bits of slightly darker stitching to give it a hand stitched look all for around $5.50 on sale from JoAnne's. I bought a large sheet of fiberboard from Home Depot for $7.00. So, all in all, I spent around $12.50 or so to make some very good looking grills.

Have you tried listening to them on their sides? That is how the cross-fired tweeters were designed to work.

I haven't got the room to put them on the sides unfortunately. I probably set them up that way when I move to a much bigger house in a few months.
