PML Differential Covers?

Was wondering if any folks on this forum had experience with the "PML differential cover". It is a heavy duty cast aluminum cover with increased capacity and drain plug. It is popular with the SUV/truck crowd for its strength and increased cooling capacity for trailer towing. Any info much appreciated.

For the price, I would suggest going with a cover that also has the stress relieving bolts, such as the TA girdle. Yes, it is a good idea. No, the PML is not what you want for an f-body.

Thanks for the recommendation. However, I have had experience with several brands of support covers and did not want to go this route with the Firehawk. Just wanted a top of the line strengthened differential cover with drain plug and increased capacity/cooling. PML is more expensive than most other covers but looks to be a quality product.
