OK, here's the poop from Mike at Pierce Manifolds:
We'd need to purchase 20 rebuild kits (10 pairs) ... Pricing would be $80 for 2 kits (1 pair). I rounded up the $ to make it easier (they're actually $39.44 for each kit ... $78.88 /pair)
The kits are high quality and complete, containing 31 pieces. Some of the other kits I've seen have only have 23 pieces, others have even less
Here's the kit:
Click to view attachmentSince Pierce is located in California, sales tax is applicable if I purchase them
EDIT: (CA tax 8.75% = $7 for a pair) (updated #s below)That comes up to $87 for one pair.
They would be shipped free from Pierce to a single address, and would need to be re-shipped out to the individual buyers.
They can be re-shipped in a USPS flat-rate box for approx $6 to anywhere in the CONUS. ($13 to CannuckLand)
So if I purchase and redistribute them:
$93 gets you a pair shipped to your door.
Two pairs: $180 shipped ($90 each pair)
Two pairs to Canada: $187 ($93.5 each pair)
If 'someone' outside of California collects the payments, pays the invoice, receives the single shipment, and reships them out to the individuals buyers, we can all save an additional $7 on each pair
$86 gets you a pair shipped to your door.
Two pairs: $166 shipped ($83 each pair)
Two pairs to Canada: $173 ($86.50 each pair)
