With the F3 setup I am putting on my F1 I ordered a new master in 5/8 per Randakk's recommendation.

Agreed, I see a set of V65 magna on facebook marketplace and several on ebay, they have the anti dive bracket. I'm thinking buy the set and worry about getting the left fork bracket later?
What is the spacing of the lugs on the GL forks? Is it 100mm? There was a guy on the Ascot forum parting one out, so I asked if the bracket was still available.
Don't fix it if it ain't broke!

 It's has the 65mm spacing according to my crude metric ruler. And yes, it has the 38mm piston stock. If I remember correctly, the guys that didn't see improvement did not mention any other caliper other than the 82 cb900 or 75 dohc.

 I figured at this price $25 plus shipping why not? I need to get my hands on some parts to measure and check out. I may have screwed up, I think his $27 ones said off a running bike.

That's a VERY good deal for two 32mm calipers! I paid $85, plus a 180+ miles round trip to Phoenix, but they did let me swap the V65 brackets for the needed 65mm brackets, that I found in a mess of calipers heaped on shelves in a narrow dimly lit isle. ;) The right-side bracket you're getting is the 100mm version, so you need brackets for both sides. Reply #66 on this thread has a list of the bikes that used the 65mm brackets:http://forums.sohc4.net/index.php/topic,89771.50.html

 Thanks Scottly. I really appreciate the help. One day this summer I hope to ride past some scenery like in your picture.

My avatar picture was taken from a support vehicle on I-40 West-bound, about halfway between Kingman AZ and Needles CA, during the first Relay. That area tends to get a bit warm in the middle of summer. ;)

 I drove through there a couple years ago, in winter and in a car. We went to Pomona for the winternationals and heard a section of the northern return route was blocked by a fallen boulder. We wanted to go south coming back anyway.
 I've been shopping on ebay. Looks like I'll spend more for the brackets than the calipers. L0L. My brother has an 82 cb750 in storage, I'll have to take the whole bike to get them though.
 Edit, I ordered a pair of cb900F brackets off ebay, I paid more than I did for the calipers but I wanted a set and I wanted them now. I did find a set of calipers and brackets with the 30mm calipers but already bought the 32's. Bigger is better in my book. Maybe I can sell the leftovers to recoup some cost.

 My 81 cb900F caliper brackets arrived today. They aren't correct. Probably from an 80 cb900c from what I can glean off the microfisches. I sent a message to the seller but he has a pretty good disclaimer on his page. Probably got hosed.
 Tom on the naked goldwing site posted a pic of the right ones.

 So, I bought these also, 30mm pistons. I'll use the 32's I already have and make a set of 30's for my brothers 76 wing.

 So what I have here are 85 VT 1100brackets and 85 VF1100 32mm calipers. I'm going to do a clean up on all of the parts and test fit to the bike before taking the pistons out for a rebuild and cleaning. I'll make a card with caliper info to keep in the bike for the day when me or some future owner need to know what the parts are. I'm considering a running tally on maintenance and parts swaps in junkyard paint on the underside of the seat.

 I decided to clean the calipers before a test fit. One was clean as a whistle, one not so much. I had a stuck piston and pumped it out with grease because I didn't want to mess up a running bike with brake fluid. It worked slick except the bleeder kept the grease gun's tip. I can't get them back apart. Looks like I have a permanent caliper adapter.

 I got them on and test rode it, I didn't want to hammer the pads until they break in a little, they are pretty nice used EBC's, I sanded them to get a fresh start and will try to break them in before doing stoppies. Even with the old hoses I can see a big difference.

 I must have leaked a little brake fluid on the rotor dangit. Since the pic I brakecleaned everything and wiped it down.

Yeah, the twin piston calipers are the bee's knees. ;D

 I had a stuck piston, air didn't move it so I plugged the banjo opening and used the grease gun. It worked great and the piston was nice after I cleaned the outer edge. Problem is the grease gun fell in love with the bleeder and won't let go. I now have a permanent adapter.

 The pads are seating nicely, I've been riding when it's not cold as a witches tip or raining.

This will be next year's upgrade for my 750F1 with the F3 front end.

Just a FYI for you guys. While surfing earlier I ran across the square profile o-rings for the calipers. Z1 has them.
As of today 3/13/2012 my original owner 75 CB750F has made it through 3 wives, er EX-wives. Free at last.  ;-)

 I raided my brothers storage unit yesterday, nabbed a small taillight and a left carb body. He has 79 and 82 750's he got from a fool that only knew how to take things apart. His 79 has the antidive forks from the 82. I suggested we measure them and try them on his cb500 sidecar bike. No brake on the sidecar so it can use some help. It has a trailer rim, I'm wondering if a trailer brake might fit.  He's determined to get back on his gl1000. I see disaster looming. He's 79 this year.
