Trying to save & use what I can, 68 Frolic, Brakes, Bearings

Now would be the prime opportunity to replace the brake assemblies and while your at it, get some drums that have a more "standard" bolt pattern to accommodate a more common wheel. I stand to be corrected, but I as long as you find a 10" brake assembly with the 4 bolt mounting pattern it should fit. You can sometimes get these with the drums with a standard 5 lug pattern (can't remember the size, but commonly is a Ford bolt pattern).
Since you're going towards Elkhart, should be able to find something in the rv mfr'g capital of the world. I've found new 10" brake sets for under $80 (not including drums). 10" 4 bolt is typically for a 3500# axle.
Just a thought, didn't say it was a good one...

Further information:
Based on previous input plus WhitneyK's thoughts, thanks, I'm pursuing the feasibility of putting on new brakes and new drums that will accept standard wheels. The question I'm working on now is, are there new drums available that will fit on my spindles? I give some more information in my original post.
I'm not a machinist, but using a digital caliper I came up with the following measurements in inches:
The diameter of the spindle where the seal sits is 1.72.
Where the inner bearing sits is 1.37. The inside of that bearing measures 1.36.
At the location of the outer bearing, the spindle is 1.06 and the IO of that bearing is 1.05.
(I realize that those measurements for the bearings as compared to the spindle would mean that the bearings wouldn't gon on the spindle. They do. As I said, I'm not a machinist.)
I don't see what difference it makes but the part of the spindle threaded for the castle nut is .73 (3/4).
This is pretty close to a #84 spindle.
At this point, I don't know about the spindle length. Does this vary, or is it standard?
My spindles have plates for mounting four-bolt brakes.
Does mounting new drums on these spindles sound doable?
Oh, for anyone who speaks bearing-ese, the bearings are Koyo, LM48548, & L44648.
It would be great to hear from someone who has already walked this road, or who has a better idea about how to walk it than I do.
Thanks,

Thanks.
I'm currently communicating with etrailer.
It seems like I can get to a point close to be sure. Closing the gap is hard, if not impossible. I am aware that the way I might have to go is a new axle. I fear that may be difficult, as well, since this trailer is narrower than many. Anyhow, it is what it is. And sound decisions have to be based on what is, not on what I wish.
Thanks

Thanks, ruderunner.
Yes, I had already figured that out about wheels. I'll have to by 3 wheels anyhow, so, as long as they are of the currently common variety, I don't care. I will get 15 inchers since that is what I currently have and I have 2 new tires.
Also, I think I can lay hands on a #84 stub spindle. I may get it, do a careful comparison with my current spindles, and maybe even "dry fit" it with my current drums. If that is a match and fit then I should be OK. I'll take that spindle back and put your plan into action. If not, that will move me toward a new axle.
Your counsel makes my mind less troubled. Slowing the cash-flow will help the marital bliss. I am rebuilding the trailer to accomodate 2 of us.

So I have seen Fayette wheels for sale off and on. You would need the brake assemblies, magnets and spring kits. Those are possible to find just would take awhile. For new brake assemblies there might be some fit modifications if you keep the old drums.

Thanks all.
I just noticed that I hadn't gotten back to this.
I'm just about ready to get Frolic on the road.
She has new brakes, bearings, drums, wheels, and tires. I also ran new wiring for the brakes.
The folk at ETrailer were a great help.
All of your posts helped me herd my thoughts in the right (I hope) direction. BTW, herding my thoughts is a lot like herding cats.
Thanks
