"Like others on this forum my linkage sticks on my hurst floor shifter"
I know the column shifters "stick" aft. many yrs., but, the Hurst & Duff shifters are bullet-proof for the most part.
Having said that, that doesn't mean it's properly adjusted...or something might have come loose. They're very simple...but don't look that way, at first. I would contact Hurst....they will send you a detailed drawing & instruction sheet.
"....and my gears feel loose and it is not the easiest to find neutral smoothly."
Worst case is; maybe the problem is in the internal trans. works.., not the shifter.
"...nor did i install the hurst floor shifter the previous owner did, but would like to know if there is an easy fix"
The shifter is easy....a 1 banana job......with instructions, the 1st. time.
I would start here....i.e. be sure the shifter is functioning properly.
"....or am i best taking it to a trans shop?"
If it is, in fact, in the trannie, You can get a good deal on a re-built....it's the remove/install that gets pricy... B)
