A pair of SRB motor plates with crossbar and screws, brand new unused. I would say get this if you have a set or plan to get the trucks on 2wd and plan to upgrade to a 4wd.
Listing price on Stooge’s site is $120, asking for $60 + shipping, which is about $15, so $75 total.
Pics are of the same mounts, i just flipped it to show the other side.
