An absolutely perfect fit in place of the vacuum pump after removing the vacuum system on my 78 Skyhawk, be sure to order SL8313 gasket also!

Its a little flat cover. Nothing special but just what we needed.

I got the part, works fine

Fit perfectly and cheaper than the Lycoming equivalent.

Fits my Lycoming IO-360-A1B6D perfectly.

Timely and correct item.

Perfect fit on O-320. I also purchased a gasket for this 1/4 plate and the accessory drive housing. No spacers needed if youre leaving the accessory housing in place.

Fit perfect for my O-360 Lycoming, and much cheaper in price. Dont forget to buy a gasket...

Aircraft Spruce has come a long way and usually does a fine job. The vacuum drive covers were fine. My only complaint is no gaskets for a $35.00 item that cost about two bucks to make.

Right part number for my engine, but it is too small & does not fit. Not sure why!!!!!!
