    I have a 95SN block with and T5 transmission with tag #1352-249

    I was told that the 95 bell housing wont' fit that transmission and I need a fox body bell hosing. I just found one on craigslist from a 92 fox body but before I buy I wanted make sure that they will simply bolt up without changing the input shaft.

    the sn95 bell and t5 are a mated pair, the input shaft is longer on the t5. When you use a fox bellhousing, you also must swap out the input shaft on the sn95 t5 to the shorter fox style too.

    You just got some excellent advice, take it and run with it.

    The 95 Bellhousing won't work properly without swapping the transmission input shaft.
    All things considered, it would be easier and probably cheaper to get a 86-93 5.0 bellhousing. Swapping the input shaft is a lot more work and expense.

    After looking at the model number for the transmission, there doesn't seem to be a longer input shat for that particular transmission. The 2.95 first gear is really good, but it is also somewhat unique among T5's.

    T5 identifier information.

    On the tail shaft of the transmission, there will be a stamped aluminum tag. The tag will have a number on it that you can cross reference to the chart below. There is no other way to find out what type of T5 it is without disassembling it. All the rest of the numbers on the outside of the T5 case are part numbers which are not unique to any particular T5 model.

    Remember that 94 - 97 T5's have a longer input shaft (about 11/16” longer) and can only be used with a 94-95 bell housing unless you modify or replace the input shaft.

    T5's used with a 4 cylinder have a 3.93 first gear, reduced torque ratings and an input shaft pilot diameter that is smaller that the T5 used for V6 & V8 engines. The pilot diameter is .59" compared to the .668" used on V6 & V8 T5's. It requires a different pilot bearing to be used with a V6 or V8. The pilot bearing you need is for a Ford Ranger diesel from AutoZone part #14672

    I don't know how you feel about the DYI thing when it comes to gears, some people don't like the idea of working on transmissions. If the DYI transmission fix idea isn't something that you would rather leave to someone else, here are some resources:

    See http://www.ttcautomotive.com/English/onlineorder/product.asp to download a FREE service manual for T5 or Tremec 3550/TKO
    You will need the Adobe Acrobat viewer which is also a free download – http://get.adobe.com/reader/

    See http://www.hanlonmotorsports.com/ or http://www.ddperformance.com for parts

    A T5 rebuild kit with syncros, bearings and other small parts costs about $160. It does not include any gears or shafts.

    http://www.hanlonmotorsports.com/ also has a video on how to rebuild your T5 or Tremec. It costs about $20, and is worth every penny of it.

    I did a Tremec 3550 rebuild, and it wasn't that difficult. The video was an immense help, and I would recommend viewing it. At $20, it will give you an opportunity to look and decide for yourself if you think that it is something you want to try to do.

    249 comes back as one of these bad boys

    It's a fox body trans, so the SN95 bellhousing wont work as it's slightl longer. I do not beleive there is an input shaft for that transmittion to work with the SN95 bell.

    You need to run a 1986-1993 T-5 Bellhousing. Part number E6ZR-6394-AA
