poyjas,
Several factors come into play, with doing an ssqa on little loaders.
Width of the loader arms, on most they line right up with the pins so you end up moving the pins out so far they make the lift loss too great.
Width of the bucket, most of the buckets on smaller loaders are narrower than the backing plate width, 46"
Weight, even with a 5/16 cut down plate and a small adapter that adds a lot of weight out front witch reduces lift.
When I built my loader for my B7100 I used the SSQA idea and made it smaller, narrower, and lighter.
I took the dimensions of the inner pin holes of the SSQA plate and used that for the new width.
Also don't use a 5/16 plate, if you need one at all (i just put the top latch plate and the bottom latch plate on the back of the bucket), use a 1/4 plate and cut it down and lighten it.
If you need more info or help just ask.
