OK, I'll walk you through this in easy steps. Most of the HJG aircraft were intended for FS9 but will work fine in FSX.
You don't say which version of FS this is for so I'll describe the install for FSX.
Download the Douglas DC-8-73 Base Pack & Transamerica repaint here ->>
http://simviation.com/hjg/aircraft/douglas/dc-8-73.htmFirst of all install the base pack.
Extract HJG_Douglas_DC-8-73_v5.zip to a Temp folder.
It contains a folder named
HJG_Douglas_DC-8-73_v5Paste this folder into your FSX\SimObjects\Airplanes directory.
Now install the texture.
Extract dc-8-73_transamerica_1983_n872tv.zip to a Temp folder.
This contains a folder named
texture.transamerica_1983_73_n872tv plus 3 files named add to aircraft.txt, eula.txt & installation instructions.txt.
Paste the
texture.transamerica_1983_73_n872tv folder into the HJG_Douglas_DC-8-73_v5 folder you just installed.
Now open the file named
add to aircraft.txt in Notepad.
Select all the text (Edit > Select All) & copy it (Edit > Copy)
Find the Aircraft.cfg file in the HJG_Douglas_DC-8-73_v5 folder & open it in Notepad.
Paste the text you just copied at the top of the CFG entries (just below the first 3 lines)
This is what it will look like:
// Add your [fltsim.xx] sections here.
// Remember to start with 0 (zero).
// Copyright Historic Jetliners Group. No uploading of HJG materials to any website without prior approval.
[fltsim.xx] // Change "xx" to next number in sequence starting from 0

Change the
[fltsim.xx] entry to the next number in sequence.
As this is your first variation it will be
[fltsim.0]Exit Notepad saving changes.
NOTE: If you have problems saving the Aircraft.cfg file paste it to your Desktop before editing it. Then paste it back after saving.The aircraft is now installed & will be listed on the FSX aircraft selection menu. (It won't have a thumbnail but that is easily fixed later.)
As this is an FS9 aircraft the panel & sound are
aliased to use the files from the FS9 default B747-400 & B737-400 respectively.
For the sound to work in FSX you will need to edit Sound.cfg to point it to the default B737-800.
This is easy enough but it might be better to download & install the correct panel & sound from the HJG site.
