...and I predicated my encouraging of replacing with the CS144 when I read your positive response about the dealer having a bracket...ugh...I feel guilty.
Now you need to ensure that you get a bracket and be sure the bracket is all you need. Parts department personnel -used to know- if a bracket alone is enough.
Tensioner?
Water pump hub pulley?
Crank shaft pulley?
Back in the eighties I changed a standard V-belt 350 chevrolet engine to the unique 1986 chevrolet ribbed but not serpentine alternator belt.
"Lessee you're going to need the alternator pulley" CHECK
"Crankshaft pulley" CHECK
"Water pump pulley" CHECK
"Reverse the pulley on the power steering pump" CHECK
Brackets do not wear out. Most larger junkyards are part of a regional or national network "hotline" for parts. Hundreds of yards linked. You need to go to your local yard in person. And sign on.
Like was mentioned. GET A PART NUMBER. Then pretty-please beg the parts man to check and see if the Crankshaft, and water pump pulley part numbers are the same for the CS144 astro van with same engine. See if you can beg the correct drive belt part number -- this is important.
Remember -- the rectifier in your CS130D alternator is marginal as is for durability. Pump up the amperage and bend over. There are NO upgrades for rectifiers. An easy-to-mount CS130-D that blows rectifiers is not worth a side order of hog snot. 99.9% of aftermarket garbage sales of a hopped up CS130-D are to idiots who stick in a boom-thud 2000 dollar stereo and follow the herd and spend money on an alternator "Eeeeewwww you didn't buy an alternator?"
Used parts will cost substantially less than new and they do not wear out...
