65-66 vs 67 KH caliper brackets

[degins]

As some of you know, I am working on the reproduction of the 65-67 KH based front disc brake system. It is common knowledge that the caliper inlet is 7/16" for 67 vs 3/8" for 66. The anti-rattle clips are different as well. I have run across another major difference that requires me to make a design decision. That is, the caliper brackets are different as well. The 67 caliper mounts holes are displaced a little (~0.125") vs the 65-66 type. In addition the bracket is made a bit beefier in a key location.

I assume that the resulting relocation of the caliper in 67 was intended to correct a minor deficiency. With that in mind, I figure that I will make build the 67 system and risk not being concourse correct for 65-66. What do you think?

Imho, if you are really wanting to bring home trophies don't give the judges some thing to mark you down for. If you want to drive it around and go to the show for fun and to check out the hot chicks go with the newer incorrect parts.

This may be useless info, but functionally, the 67' Ford caliper brackets work just fine on the 65' spindles. I've been using this combo for years with the 67' hoses and never knew there was a mounting difference. I have only purchased the 67' calipers throughout the years, mainly because of the differences in the anti-rattle clips. I just wanted to keep the system that I had, without the added expense of converting. Never tried to mount a 65/66 caliper on the 67' brackets.

I have also found that the piston dust shields (and the way they attach) can vary too when one is rebuilding the calipers. The aftermarket kits do not support both versions.

As I mentioned in the other thread I think the 67 is a better choice.
If the person it looking for concourse correct they have other options. But I would think most of us are interested in function much more than points. I think the 67 was changed with lessons learned from the earlier years.

This is also weighed buy the fact I have a 67 and feel it is the best year.
