Have a pair of Carrera(?) threaded aluminum body shocks for sale. Marked 6253/1 on each also marked 1-2-3 for adjustments and has "ARS 4719" and "ARS 4720" on the other one. Both have spherical bearings which don't feel loose.
These came in a box of parts I got with a car I bought several years back and I have never used them. They feel good pulling out and pushing in but I do not know actual condition.
