Replacement shocks

[wldgtx]

So this may sound like a dumb question, but I am going to ask anyway. I need to get new shocks on all four corners of my Hemi GTX. There are two options when looking at replacement in the black factory style (Standard & Heavy Duty). Given the fact that this is a Hemi car, 4 spd, my gut says the replacement would be the HD, but I am not 100%.

Am I off base with this assumption, I cannot go off of what was on the car because the previous owners replaced the originals with aftermarket ones.

Thanks all.

HD is correct. RTs and performance cars had HD suspension pretty much standard. Now the fun part is picking the best replacement ! Good luck
