Need stereo bezel for 89 quest black preferably

My Maf sensor is bad on my 89 quest is there an upgrade or where can I find replacement

The diff is a little dirty from use but didn't leak and locked up very well. The torque tube had no clicking and is tight. The axels move freely but have a little surface rust.   $100 per axel $100 for the toque tube $100 for the diff   These prices include shipping and if you buy as a package I can make you a deal.   http://i17.photobucket.com/albums/b84/trippleCing/FOR%20Sale/51F80354-6D87-49C1-BC95-2802EE0BEAB8_zpscmtz3j3z.jpg   http://i17.photobucket.com/albums/b84/trippleCing/FOR%20Sale/

I can reuse my parts store diff bolts(even if its a pain) but I need the dust cover for the front bottom on the bellhousing with bolts if possible.
