Bolt Information
PML includes mounting bolts with all differential covers.
PML provides bolts that are longer than the stock bolts since the flange
on PML's cover is much thicker than stock. The bolts with the stock
cover will not work.
GM has used four different bolts on these differentials so to
complete your order, we need to know which bolts you have. These
differentials have used both metric and standard cover bolts. The bolt
length has not been consistent either. When ordering one of these
covers, you will need to pull one of your stock bolts out (a top bolt is
best) and measure the length and determine whether it is metric or
standard.
- Bolt length is measured from the underside of the head (where a
washer would sit) to the tip. If the bolts are metric, the length will
be 21mm or 16mm. If the bolt is standard, the length will be 5/8 inch or
7/8 inch.
- Metric bolts will have 20 threads per inch, standard ones
will have 18. Also, a bolt head with lines or letters on it is
typically standard. A bolt with numbers such as 5.8, 9.8, 10.9, or 12.9
is likely to be metric.
We know this is a hassle, but we do not want to send the wrong
bolts or charge everyone a lot of extra money to cover sending all
possible bolts with each cover.

Temperature Sensor
This cover can be machined for a temperature sensor. The sensor
will be located on the face of the cover and will point toward the rear
of the vehicle. If you would like PML to machine your pan for a temperature sensor, there is an additional charge of $40. Please include temperature sensor size in the order notes, or you may order over the phone to insure accuracy. 888-832-5248
