Should be the same good old 10mm allen bolts. The only difference is that they kept upgrading the kilowatts on the starter. The first was an SR61X, then they went to SR67X and I can't remember the # on yours. In 85 the starter is kinda mounted upside down which makes it easier to undo the electrical. You should be able to snake it out the bottom by turning the wheels to the correct position. I have never had to undo steering linkage. I've done dozens and dozens.

Good luck.
Peter
