I hope this could help out a fellow member. I have a set of Poly tubular LCA and a Poly adj PHB off my 01 Bird. Im not the original owner of the car but it looks like the LCA "might" be SLP and the PHB a Lakewood. They are used, geaseable, Bushings show some deflection, unkown mileage on them. Car has 48,000 when removed. I removed them to make way for Rod ended stuff. Maybe you could use them. $80.00 for both items plus shipping.

C-5 brake Brackets for Ls1 F-body
Again Im not the original owner of the car. Unkown manufactor,(I do know they are not Bob B Brackets) Unkown mileage on parts, at time of removal car had 36,000 miles. They are steal brackets that adapt c-5 calipers to an F-body using original mounting holes. The odball part of this is that it uses C-4 rotors(13" diameter rotor) and stock brakes hoses will work. I have a box of stuff you can have. 2 Mounting brackets,2 Calipers and Abutment brackets with attaching Hardware) and even brake hoses, I even have the brake cooling ducts brackets off the car in there too.. It was fully fuctional when removed, car had OT track time so it did work at track. But with that said All Parts are used showing normal wear and tear, No guarantee implied or given. $200 OBO plus shipping

I've been able to verify that the calipers I took off are infact c-5 ones.
