I put in an order with https://www.energysuspensionparts.com/
( they are not energy suspension but they carry their products ), and we will see if the listing showing that they had the parts in stock was accurate or not. I asked for a call before shipping anything if they could not do it in one batch order.
I ordered the following for my C53a, using C53a control arms and their matching rear style mount:
SPF1160K Front lower control arm inner front (press in halves - no outer casing)
SPF2026k Double offset front lower control arm inner rear - GSR turbo style fitment X1 bag (contains two bushings, one for each side)(cased bushing designed at press into factory mount, mount is removable with two large bolts and one large nut)
SPF0427K Rear panhard bar bushing X2 bags (each bag does one end of the double ended bar)(no outer casing lots of grease required to press/ squeeze into place)
I already have 20mm Elantra/turbo sway bar frame to bar bushings in place, and the turbo control arms do not require stabilizer link bushings as they are double ball and socket style.
