So I can't find a t17 torx bit that fits the bolts on the TPS bracket. I've been making a 15 and a pair of vice grips work but that has come to an end and it's just a crappy halfA way to do things.
So, does anyone know...
-where I can get a T17 bit
-where I might get replacement bolts
-if I can swap the bolts for some Allen head ones that are threaded all the way?
Not an emergency, bc I'll just do some fancy work on these to make them work, I'd just rather it be a little cleaner than my engineering.

Mine isn't hooked up but I believe it should light up, if I remember correctly when you turn the key on prior to start up. I bet the bulb is bad.

Does the antilock/speed sensor on the rear diff on my '91 tie into the trans also?
Because my light is on, I've done some wire checking but how do I check the sensor? Saw a post on it, but it didn't seem right.

On a 91 the VSS is on the tranny 
Erratic Shifts
Bad VSS
Can cause erratic shifts and LU problems. May or may not set code 29/452 (VSS speed
sensor signal to low).
Note
VSS is located in transmission tail housing or differential.
To check VSS
1. Remove 2-wire connector end.
2. Hook DVOM meter leads to pins on sensor. It doesn't matter which way you hook
up the red or black leads.
3. Set scale to AC voltage / 0 to 40 volt scale.
4. Raise vehicle so rear wheels are off ground.
5. Start vehicle, put in 'D" and make transmission upshift. Watch meter.
6. You must see an increase in AC voltage or VSS is bad.

Ok, yeah that's the info I saw. The AC voltage setting is what threw me off and just wanted to be sure it wasn't a typo.
It's no secret I'm lackonh electrical knowledge, but it's doubled since being on here and "building" this truck.
Thank you, I'll report bk tomorrow with findings.
