1998-1999 S10 ZR2 lower control arms are OEM only
Wanted to post this as there is very little on this anywhere on the internet.
The Lower Control Arm for a 1998-1999 ZR2 is unique. GM is the only provider of this LCA, their are no after market equivelants. I went so far as to talk to MOOG directly on this.
For reference, the OEM part numbers are:
15777765 driver side lca ZR2
15777766 passenger side side lca ZR2
The following part numbers may be OEM substitutes:
One dealer in the USA had the 15777765, they are in TX, I purchased this earlier today.
Ebay does have these part numbers show up on occasion by OEM part liquidators.
I am going to keep the original LCAs from the ZR2 , rebuild them, and keep them as spares.
