This diff cover fits the GM with 7 1/2" (7.5") or 7 5/8" (7.625") ring gear 10 bolt differential. Typical applications include the following. Be aware that for each model and year there maybe more than one rear axle possible. See also the PML GM 10 bolt 8½cover.
Some vehicles have brackets/cables on or near the stock cover. PML does not have any information on modify these to work with our larger cover. Such modifications are the responsibility of the installation.
Configurations vary. Always check your vehicle to verify differential and clearance.
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.
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. Watch the video for more informations on checking your bolts.
