MG Car Repair: 1976 MGB No Reverse, forward gears, clutch master

Question
I've been working on this MGB for the last week. It's been sitting for the last, probably 5 years or more. It took almost half the week to get it running, then the last couple of days rebuilding the Clutch Master and slave and running new lines. Now that it runs and the clutch works, it shifts into all 4 forward gears no problem, but there doesn't seem to be a reverse gear. Normally you pullover to the far left then back for reverse, but there is no far left to pull to with this stick, it just stays in the 1st and second line, any clues?

Answer
Hi John,

There is a detent that prevents you from entering the reverse pattern by accident and it may be rusted. So do this,

Put the shift lever in the neutral position all the way to the right side and place your open hand further to the right about 6 inches. Then strike the shift lever to the left firmly with your open hand. If that don't free up the detent, you will need to remove the tunnel carpet and top cover at the shift lever and try to spray some lube down into that area. You can't access the detent from there but you may get some spray lube in that area enough to break it loose.
