TR2/3/3A Mounting Toyota Brake Calipers on my TR3

I've read all the pros and cons of converting to Toyota 4 pot brake calipers and all the articles are relatively clear on the procedures for mounting, based upon the TR6 brake caliper mounting bracket. As to the TR3 it simply states that you need to swap out the TR3 mounting bracket for the TR6. Sounds simple enough. So after sourcing a TR6 brake caliper mounting bracket (which I confirmed was from a TR6) I attempted to exchange the brackets. The bolt holes are not even close to the same configuration no matter which way I try to align the bolt holes. The articles all talk about the bolts and threads and such, but I can't even get to that problem. What am I missing?

I don't know why you should be having a problem. I took the brackets from a TR6 that was being parted out. They look different than the TR3 brackets, but they fit fine. I used the TR3 mounting screws. Below is a pic of the two different brackets. The one on the left is from the TR6. Maybe you didn't get TR6 brackets.

Here are good articles on the Toyota caliper install:

Also when I did this conversion on my TR4a, I bought special flex lines (rather than making the metal ones as in the article) and new mounting bolts, from these folks:

I think that Marvin has answered my question. The calipers are 16PB and the mounting bracket looks identical to the one martx-5 posted, except the bolt holes are in different locations. I think that I need to find a different set of brackets. Thank you

Bruce, when you get it all buttoned up and tested, I would like to know your thoughts on the new brakes.
