FWIW: The Delco PN# for their 2 qt filter is PF932. Had the local Advance Auto store order in a half dozen for me. Don't remember the unit cost, but not enough to break the bank. It is stickered with a "Product of USA" label.
I know we used to sell class 8 rubber flaps at OReillys; I think the size was 20x30. Bracket kits are available from any number of big truck parts suppliers. The ones we had were scored for easy size reduction.
You didn't mention if your truck is 2wd or 4wd, or 1500 or 2500? Also, where did the 7300 GVW number come from? Door jamb sticker, RPO sticker? Diesel or gasoline?
Maybe someone can explain why you can't buy the vehicle? Here in Texas, we have our wholesale auto clearing houses, which require you to have a DEALER license to buy at one of their auctions.
Here's another one if anyone still needs one:

John,
This one popped up on e-fleece this morning:

IMHO, buy it!!! Rust free burbs are a rarity these days
Just finishing up my 1991 V-1500 GMC Suburban. You're lucky it's an '87, as most parts are available. The 1989-1991 burbs are where you have problems finding parts. A lot of the new features for the new GMT-400 trucks were incorporated...
There is an post from earlier this year that has a member's solution for filling both tanks from either side:

Welcome to the forum from N. Texas!
You're extremely lucky to have found it again and then re-purchase it.
My vote is to take it back to stock height, but that's probably my age talking.
Good job on the paint restoration!
