i use Gabreil red ryder gas shocks from a f-150 pu . 2wd.
the lenght is just right and there cheap like $9.99 at the auto store ..
its a cheap way to see if they will work for you
1 hour and 20 bucks..
my 3410 duster goes 1.39 60 fts with these and its on a small slick. 10"
for the cost its a no biggie if it doesnt work as aposed to $89.@ shocks just to find out there is no improvement.
cheap.
