Note: 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. (Yes, this is a pain. However, the bolts and drain plugs are stainless steel and expensive. We do not want our customers to pay extra for several different sizes with each cover.) Here are some guidelines:

• Bolt length is measured from the underside of the head (where a washer would sit) to the tip.
• 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.

If you order on-line, please note the length of your stock bolts, and whether they are standard or metric in the vehicle information section when placing your order so we can provide the correct bolts.

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. See image (click here) for an example. Please call to order if you would like a cover with a temperature sensor location.
