QA1 Promastar, single or double adjustable. Dont know the exact lenght, you have to measure it. Stock irs shocks are about 11"-16".

Use around 350-425 lbs springs with stock weight drivetrain and mild engine, more hardcore motor etc maybe 450-550 lbs springs.

On steel irs arms you might have to drill another hole to the arm, see here:

Here are QA1 shocks on aluarms at Humbles car:
