[Shotimes] 95 MTX failing in high heat

[Jon Heese]

Yup, they're available, but they're not cheap:

Looks like $211 at Advance and $129 (possibly dependent on your zip
code) at Autozone:

http://www.autozone.com/selectedZip,77346/initialAction,partTypeResultSet/initialN,16200029/initialNtt,/initialNo,/shopping/selectZip.htm

Alternatively, there are a couple on eBay right now for $17.99+shipping
and $49.99+shipping, respectively:

http://cgi.ebay.com/ebaymotors/THUNDERBIRD-SUPERCOUPE-TAURUS-SHO-DIS-IGNITION-MODULE_W0QQcmdZViewItemQQitemZ250263329641

Both are used, but that would be the way I'd go if I were you...
