If I recall there are two shoulder bolts that pilot/locate the side cover. One in each end if I recall. No reason to loosen bolts and tap the cover if these bolts are properly located.
If the shifter moves freely there is no issue. What you likely are feeling using the operating lever is the decent mechanicism rolling over the detent ball. Much like an auto trans lever rolling over the detent ball. As you go over the tip the effort rises then falls.
When adjusting the shifter you are supposed to place a drill rod or hex into the bottom of the shifter to align all the shifter levers in the neutral position before adjusting the rod ends to engage the shift levers in he cover.

Good advise, but there are occasions where you need to "swim" the side cover around to achieve smooth operation and proper detent, alleviate binding, stiffness, etc, etc, esp when the OP has had it rebuilt/serviced and it really hasn't seen any usage, a lot of factors here we can only surmise at... We'll assume the OP is well versed in shifter set up/assy and operation?

Ok, I get that. We are going to try removing the detent mech. first. We adjusted the 4 forward speeds as you outlined. The reverse levers were adjusted as both the lever on the trans. and shifter were engaged in reverse. So ixnay on the ackway.  we won't be banging on the cover. Maybe I'm reading it wrong? regarding your shifter adjustment procedure... looks like a case of back to basics is needed first, remove the shifter rods all 3, the transmission needs to have all gear lever positions, reverse included in NEUTRAL position The shifter needs to be in the neutral position, you need to insert a rod/drill (1/4" IIRC) bit thru all 3 shifter arm pilot alignment hole, then adjust the shifter rod swivels/ends to fit freely into their corresponding holes, reverse included Now if you have an aftermarket shift box with shifter stops, that will be another adjustment Mike

There is a special lever alignment tool for Mopar Hurst shifters with only two alignment holes.
As to the stiff Reverse, there is a tang on the internal Reverse lever that interacts with the interlock to prevent Reverse from engaging when in a forward gear, if the tang is to close to the interlock and rubs, the lever will be stiff. Loosening the cover bolts and repositioning the cover will usually make the lever move easier.

Just found that there is no alignment hole for the reverse lever on TWO '68 shifters. We are going to remove the detent ball and spring to see if that's the problem. If not, we will reinstall and try "swimming" the cover. Thanks again! You can either buy/borrow the tool or drill a hole in the reverse shifter lever, forgot about those 68 Inland shifters...sorry

Without the tool it's trial and error. Use a 1/4" rod to align the 1-2 and 3-4 levers with the housing, then install the 1-2 and 3-4 rods. Play with the Reverse rod adjustment until you can shift into Reverse without having to move the shifter for or aft as you pull the shifter towards you.

This may be what you are fighting. The earlier FSM's actually reference Dayclona's comments about tapping the side cover to get the correct "feel". I have run into a couple transmissions where I had to carefully grind the interlock lever surface to get acceptable performance.
