I am about to convert to the Fox TB for the reason that they dont make one big enough for 94-95 cars. Unless someone knows of a TB bigger than 75mm. If so please let me know. And does anyone have a thread on the complete how to Fox conversion I cant find it. I want to keep my Cruise Control. I need at least a 90mm

There was a decent thread a while back about the Fox TB conversion. Keeping cruise is fairly simple. Buy a Fox cruise cable from a junkyard or 5.0resto or somebody and put it in place of the SN95 cruise cable. I did it and it works great.

Here's how to do it:
You'll need the following items:
Fox TB
Fox TB IAC (you can use the SN IAC but it looks Fugly and you may have hood clearance problems)
Fox Throttle cable
Fox Cruise control cable
Fox throttle cable bracket
Fox Fuel injector wiring harness side of the TPS sensor
Fox EGR valve (and a 5\8" cap to block off the EGR port on your header)
Fox EGR spacer if not using a '93 Cobra intake or EGR delete plate to mount throttle bracket
Fox Vacuum tree (available at 50resto.com like most of these parts)
Tubing to run from the VC filler neck to the TB PCV tube connection if not using SN95 port
Vacuum caps if you need to block any connections off if you've deleted EGR etc.
a 3\8" pipe plug to block off the Fox ACT sensor port behind the #5 runner in the lower intake if you are running a Fox lower intake or aftermarked intake (or simply use the Fox ACT sensor as a plug for the hole)
You'll have to modify your SN CAI or modify a Fox CAI, or make your own. I have pictures that I can email you.
Here is the TPS wiring splice directions:

I think 75mm is as big as you can get in a 94-95 TB. But here is an accufab 90mm that fits a fox! http://http://cgi.ebay.com/ebaymotors/Mustang-Accufab-90mm-throttle-body-polished-5-0-Mustang_W0QQitemZ270127506541QQihZ017QQcategoryZ33730QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

I made a thread a while back ....I think it's in the sticky up top. Just use a fox cruise cable... it works fine.
