sloppy 4 speed

Drove the Charger yesterday for the first time to determine any mechanical faults on the car. The only problem i came across was a very sloppy gear change ( Hurst 4 speed ) Im pretty certain its the selector mechanism bolted to the gearbox where the stick shift attaches.

Would this part cure the problem ?

There are various things to check before buying a new shifter. Things come loose, check the shifter is not loose on the box, shift arms tight? play in the arm to rod bushes or the shifter to rod bushes? Hurst used to sell shifter rebuild kits, not sure if they still do.

There's are a LOT of moving parts in these shifters and room for play in all of them!
The clip on Wheeler dealers missed a lot out, for example the correct way to adjust the linkage lengths which is CRITICAL!
Check rods & ends for play, check rods and arms don't foul anything. Remove your shifter and clamp it in a vice, refit the stick and play around with it, you soon see if it's worn.
You'll see a drill hole through the bottom of the plates which corresponds with a hole through each shifter arm. Find a drill bit or bar that's a good fit.
When you refit it all put it in neutral, pop in your drill bit and adjust each rod in turn so it drops onto the gearbox shift plate (these also wear!).

If you want a replacement unit, Brewers are the best. They do rebuilt shifters for around $200, though there's a core charge if you don't send them your old one so you may be better just buying new.
Make sure you get the correct serial number shifter, there are loads of different types-

That'll do it, but a drill bit will work just as well if you want to save time and money :thumbright:

Just use a 1/4" drill or a length of 1/4" bar.

Blue has done that mod to his car. A great idea if you're gonna hammer it but a well adjusted stock setup is fine for normal use.
