You will have to add upper mounting bosses to your frame. Nutserts, or similar should do the job, no welding required. M6 1.0 thread pitch

For what you're doing a reproduction makes sense...a minty-new part for half the cost of rechroming an original. There is only one repop, chp.

Thx for the information on on engine guard for my ct70 clone I don’t seem to have anything to attach the bosses you referring to on the frame.
Of course not. The Chinese knockoffs/clones are based on the 12v era frame. Honda eliminated those mounts beginning with the 1980 model CT70.

You will have to drill holes in the frame, then add threaded inserts...or welded bosses. Nutserts don't require welding. They're available in a number of different flavors; the link I provided is just for basic info. I'd fab a backing plate, from a scrap of 0.125" steel, use it as a template to mark & drill the frame, then to add strength the the nutsert installation.

I had bolts welded inside the holes I drilled. 3 anyway. The top right couldn’t be welded due to access. I used a nut and bolt there. Access with a wrench through the wire loom grommet. Honestly Racers approach would be better. welding in there is tough.

I toatay get it I’ve seen stuff like that done on Car’s. I think that’s way over my head maybe in the future. I wish you were my next door neighbor I’ve learned so much on this great site. Thx to all of you.

Don't sell yourself short. It's not difficult. Mount the engine guard to the engine, then see where the upper mounts want to be, on the frame. That'll get you close. Plus, the chp repop guard is made from thinner wall tubing than the original, which will allow you to tweak the tubing...not tools needed...if you need to do that. An assistant, or C-clamp, can hold the guard in place, while you centerpunch the frame, to locate the holes. The drill will self-center on those little depressions. From there, it's merely a matter of using the proper size drill. Nutserts are set with the their tool, a simple piece of hardware and the installation is virtually foolproof. You could use thick washers, on the unseen ends of the Nutserts (inside the frame) those serve dual purposes...a little extra material thickness, for a good, solid, compression fit and, reinforcements. I think that 1/8" (0.125") sheet steel, cut to an appropriate size oval (to cover both mounts) would be better and easier...and the templating would be straightforward.

All of that having been said, if you feel that this is beyond you skillset...and too far outside of your comfort zone...then you may be wise to not try. I don't like to think in those terms. IMHO, anyone who can assemble, modify and tune one of these bikes should be capable of tasks such as this. You, of course, are the best judge of how that plays-out in reality. I'm sitting here behind a desk, hundreds of miles away. A machine shop may be willing to do this, it'd be a really simple job for a journeyman.

Thx I can see it in my mind love the idea of mounting first then using the punches I may try it this winter. Ps. I’m with the teamsters union and work with great people that will galdly help.
