I cannot speak to you model but have done work in many car doors that my fat arms did not fit in. My #1 solution is to teach my sons with thin arms how to fix it. :)
Things I have done for tight spaces:
Use a magnetic pickup tool to place the nut on and then get the first few threads started with that. You will need one with a strong magnet.
Bought cheep sets of Pittsburg wrenches from Harbor Freight and ground them down or bent them with heat to get them to reach where I had to get to.
Used coat hangers and hot glued the nut to the end of them. Great to get the nut started and then it can be scraped off with a metal rod.
I have a set of sockets with universal joints on them that I have also used to get into tight places. I prefer the ones with the socket on the joint so it can get into tighter spaces. I have the Duralast ones but they are similar to these at Amazon:
U-Joint SocketsHope one of these solutions help. Sometimes I find the way to a solution is to sit between the project and my tools drinking a cup of coffee and just looking what will fit, not necessarily what is stopping me.
