Fiberglass Trunk Strut Issue

Ive recently purchased a Fiberglass Trunk for my 89 Hatch mustang since my old one had rotted away. I got one from harwood installed with no issues, but I need struts to hold up the hatch. The pressure from the stock one will probably punch a hole through the thin fiberglass so Im not quite sure how I should mount the struts, or which ones to buy. Ive asked for help from Harwood, but they weren't much help. Any suggestions would be a big help, thanks.

I’m not sure about the answer yet, but I’m pretty sure the first question you’re going to get is …… do you have a “notchback” with a trunk…… or an actual hatchback.
You reference both trunk and hatch in your post.
 
The OEM, I believe, is 14 lbs. For fiberglass, I imagine you'd need something in the 5 lb range.

The other relevant features are:

  • Extended Length: 29.06 Inch
  • Compressed Length: 20.47 Inch
  • Stroke Length: 8.58 Inch
  • Shaft Connection(mm): 10mm
  • Body Connection(mm): 10mm

You might have to fish around to find just the right one.
 
Just found the strut that Redline currently carries, Ill talk to a rep tomorrow when their open to get more information.

I’d have to say, after just replacing my OEM hatch hinges….. that hatch is far more than 14 pounds……. Or I need to get back in the gym ASAP!
