Re: switch auto to manual?
Personally, anything can be done. It's a matter of finding parts that can match up. In most cases, manual transmissions, let alone for the '95 styled trucks will be few and far between to find. You can contact Keisler Auto, or Richmond Gear (search Google for websites) and they might have some kits that can help you out. Their kits change every few years though, and you will pay top dollar for a newly built trans.
Personally, if your auto still works fine, leave it alone. When the auto starts to go out or flat out dies, then you might find spending the extra $1-2K on a manual transmission conversion worth your while if you plan to keep the truck that much longer. Replacing the Auto trans will run $2-4K depending on shop labour, parts used and warranty - if any.
To do the swap you'll most likely have to change the bellhousing to fit the manual trans, and with it being a '95, I think that was the year that OBDI emissions came out, so you'll have to play with the PCM (custom programming) a bit, or you'll get engine lights saying that the automatic transmission is malfunctioning, etc, when in fact it's been replaced, lol. Anyway, mounting points might have to be altered, along with the installation of a clutch pedal and other associated hardware. If you have a column shift on the F150 now, you'll have to get someone to machine a hole in the floor to accept the stick.
Not to deter you from doing the swap, as a while ago I considered getting one done to my '00 Durango R/T. A kit from Keisler was available, but I was too busy to see it through and now the kit is no longer available. It was a kit made for Dakota (2wd) trucks, but with some extra effort, and my wallet, I could have made it work for my application. Ah well.
