It seems rare to find the retaining clip hole in aftermarkets, even customs.
I ordered a brand new pair of 96-97 mats on eBay, double-checking with assurance from the seller that they were the saddle colored ones. The seller even put a label on the top with the correct Ford part number after checking them. Nope! Seller must be color blind, because I opened the box to find gray ones instead. After numerous attempts to find OEM saddle ones, I've given up.
Most custom aftermarkets are pricey. Some have fine serging surround and the manu will even embroider your choice of logo. Then there are the various piles, materials, etc.
Are you attempting to achieve the same results as custom aftermarkets but on a budget? I have the '96 OEM's if they differ from the '95's and you want measurements.
At this point, with mechanical probs needing taken care of on my Bird, I'm reluctant to dump a lot of cash into custom mats. Too bad nobody sells just the driver's side, because my passenger side looks almost new -- the driver's side is worn down to the rubber where my accelerator heel rests/pivots, and is long overdue to be replaced.
I've been considering just using clear vinyl aftermarkets, perhaps oversized & cut to fit.
What do y'all think about the clearies? They're cheap and easily cleaned. If they get stained or damaged, they're inexpensive enough to discard and replace w/o much heartache.
How about cutting to fit an alternative, say an office chair carpet protector? They have spikes to keep them in place. These are available in non-rigid material as well, so perhaps they could conform, this stuff is even available by the yard off a roll.
