For the wheel... The bolt pattern for a 2001 Blazer is 5 x 4.75" (US standard). This is for the 4WD model, the 2WD may differ.
Having the same problem on a 02 2wd Blazer. It pulls the cables tight but will not stay down as well.
Under the intake manifold, sucks but enjoy!
The flashers are located on the top of the steering wheel like they would be in a 2005 Chevy trail blazer.

on a 91 blazer s10 4wd
When new they got about 20MPG I (this info is from an 84 suburban half ton 2WD, a 93 half ton 2WD ,83 blazer and an 84 half ton pickup 2WD.
Any year 4L60E (automatic) or NV3500 (manual) transmissions will. If you have a 2WD Blazer, then it needs to be a transmission out of a 2WD vehicle, and if it's a 4WD, then you need a 4WD transmission.

It actually screws into the middle of the cat.
