I don't know about Motor mount bolts from Colony, but I just tried to install their rear stand bolt kit. It fits but it is so soft that I stripped one of the bolts, and one of the nuts. They felt like they were just compressing the split lock washer and the cupped large area flat washers. No I did not use a torque wrench. The nuts were snugged up using a 6 inch box end. Some of the other Colony bolt kits that I bought were great.

Don't you just love the research, in then process of dialing in a 40 U. Trying to find the top motor mount bolt, it's a odd one.
Darn I thought I had a picture of it, it's crown is kinda beveled to sit in the throttle harness. Guess i am bordering on hijacking this post.

Vato amigo, forget Colony. Call Old Dude, talk to Bart. He'll have everything you need, all the right stuff in the correct finish, be it cad or Park. When I call, I always have a list that I've generated from the Spare Parts catalog. But if you don't know the part number, just tell him what you need, he'll know.
He parkerizes stuff right there, so if you need something odd or different and want it park'd, he'll just do it for you. And he ships stuff out no later than the next day.

Colony fills a big void in the fastener market, but some of their stuff is better than other. Their kits often cover a wide range of years, which therefore overlook certain details; for instance, the motor mount nuts are crown nuts up until ... uh, 1950 I think, then they changed to cad plated flexloc nuts, which aren't in the kit. So those are the kinds of things to watch out for with Colony.

Personally, I always turn to Old Dude first. It's good stuff, it's the right stuff, and they know their business. But the cost of fasteners will add up fast. Imagine what it's like for someone like me, who needed basically ALL the correct fasteners on the entire ('52 FL) motorcycle. I've been buying them in small quantities for years, and I've spent hundreds and hundreds of dollars 'getting it right'. Imagine what it would be like without Old Dude and Colony. Hardware store nuts and bolts! Yikes!
