Pre-Production '91 GT?
I'm looking for any information I can find regarding the original dealer documentation on my '91 Mustang GT convertible. The other day I was digging through the original documentation that came with my car and I found the original window sticker. I was kind of surprised to see the words "Vehicle is Not For Sale" in several places. The invoice was also made up without EPA ratings or a total vehicle price. Under the EPA ratings area, it states again, "EPA data unavailable—Unit is Not to Be Offered For Sale."

I've owned this car for five years and, to be honest, I'd never looked that closely at the documentation that came with the car. Does the statement "Not For Sale" mean anything? I was thinking maybe it was a special order car, but after looking through the rest of the documentation, I found a plastic baggie that holds the original owner's manuals and it's stamped with a decal: "Ford—UAW (United Auto Workers, I assume)—EI," and below that it says "Employee Involvement—Quality is Job 1."

Is there anything special about this car? Could it possibly be a pre-production car? All of the manuals that came with the car are '90 editions, even though the car itself is a '91. There's no guarantee that these manuals came with the car new, but all of the other documentation matches this particular car. I can't see someone going through all of the trouble to track down an entire set of '90 literature to throw in the trunk of a '91 Mustang.

I've included a photo of the original window sticker. I'm curious if anyone else has ever run across anything like this. For all I know, it could be nothing special.

We've heard all sorts of stories over the years, like cars supposedly sent to the crusher that ended up on Ford's employee sale lot instead. Thirty years later someone is scratching their head during a restoration when they find something strange about the VIN, build dates, etc. One of the "flags" for us is the selling dealer—Jacky Jones Ford in Cleveland, Georgia. Jacky Jones is known for his performance history and tight dealings with Ford, including being a press fleet location (many Ford dealers were used to maintain and store press vehicles in the '80s and '90s, though Ford has moved that business on to outside contractors these days). We forwarded your question to John Clor at Ford Racing, where he is jack-of-all-trades, writing the content for Ford Racing's e-blast newsletter, handling club relations, and more. John replied:

"I have come to the conclusion that you'll never really know when it comes to anything that goes through Jacky Jones Ford! My suspicion is that it was a PP (pre-production unit) that may have been ordered for use as a Ford marketing/press car, as Jones would be the dealer in that area for regional fleet delivery. But I'm not sure, so I ran it past my in-house Fox-body expert, Nick Terzes. See his note below; seems to make sense and to support my theory. Even a Marti Report can't prove internal use. Actually, there are more PP3s, PP4s, B-Lot, and former Ford Marketing/Press units out there than you might think."

And Nick added: "This is a cool one. It certainly appears to be an early production model based on the low VIN. I suspect that it was a marketing unit that was ordered before final certification was achieved, so when the original window sticker was produced it didn't have the final figures on it. Even today, the Monroney sheets on early cars will be lacking info until we get ‘OK to Buy.' I'm surmising that back then we may have simply picked cars that were early orders in the order bank from dealers.

Cleveland Rocks (an SN95)
I would like to install a 351 Cleveland into my '98 Mustang GT convertible. Are there parts or a kit available to help me do so? I'm looking for things like an oil pan, headers, engine mounts, a K-member (so the engine will sit under the stock hood), etc. I plan to use a built-up AOD four-speed automatic. Right now the vehicle has the original 4.6L Two-Valve with the 4R70W four-speed automatic.

Fitting a Cleveland into a '96-'04 modular-powered Mustang will indeed take a K-member swap. You can use the '94-'95 K-member, but it won't lower the engine. You can find lowering mounts (though they are solid metal), and a couple of companies offer K-member spacers, which might raise the nose of the car more than you like (requiring lowering springs to get the nose back down). An aftermarket K-member—such as those from Team Z Motorsports, UPR Products, Griggs Racing, and others—will be your best bet. Some even offer the mount pad in a lower position. If you're looking for a one-stop-shop solution, you should try D&D Auto Specialties (; 610/759-2492) as they have 351C swap parts in kit form for Fox and SN95 Mustangs.
