This is getting interesting. More members need to chime in on style parking brake ratchet they have. You can feel the difference with your finger to see/feel if it has a slot on the left of the bracket or if you feel the end of the spring around the top hole. Be sure to list the year
I found this spring on the internet last night. Looks like it might work. It's actually advertised to fit: 91A-2788 39-42 Passenger 39-42 Mercury 39-47 Pickup
I got the spring to work perfectly but it took a bit of fiddling. This spring is much larger that the stock Maverick spring. I had to take one coil off and do a little reshaping then everything went back together perfectly. Some irony, I spent hours cleaning and organizing my garage looking for the lost spring but and hour after I installed the new spring I found the original. It popped into a small tray of nuts and bolts that sat on my work bench. I like the way the new modified spring works so I'm not going to mess with success.
