I put up with the original FM radio in the FB for a long time, but 2GB finally drove me mad, and the "radio in the glovebox" option got a tick

. I had originally mounted two rear speakers (6x9s) on the rear parcel shelf (I promise I did not cut the rear parcel shelf... someone had butchered it long ago, and the trim had long gone too). The 6x9's looked like crap though... the FB was looking more like a Zim Pirate mobile than a GMH daily driver. After some mucking around, I managed to mount the 6x9's under the rear parcel shelf, and remade the parcel board. A splash of grey vinyl, and we're looking a lot less like a Zim-mobile (I was getting worried... thought I might have been tempting a visit from Axeman!

).
My rear parcel shelf steel has holes in it (from the historic butchering), as does the masonite board I use for the trim. The vinyl I trimmed the parcel shelf in however has no holes, and the sound quality is very muffled. I know it's never going to be perfect, but I would like to punch some "breather" holes in the vinyl to let the speaker work better. I would like the two sets of punched holes to look (roughly) original (pedantic, I know

). I vaguely remember that the original rear parcel helves had holes punched for the optional centre speaker. Can someone post a picture of the original hole pattern please?
I can punch the holes out either with a (very) small wad-punch or one of the plier-type punches used for leatherwork - anyone had any experience doing this with either tool?
Cheers,
Harv.
