Great feedback. The cars I worked on didn't have the stiffen plate so I wasn't sure if needed to be replaced.

This tool might work to adapt a straight ratcheting wrench to a low profile ratchet and also be an option.
I used this set which I coincidentally keep under my passenger seat.

Extremely useful set only downfall is no extensions so I bought a couple.
If you read the reviews you'll see complaints about no 16mm. There is it's just called 5/8". Strangely not mentioned or labeled as such. My impact socket set has the dual sizes labeled as such eg 3/4" = 19mm. There are about 4-5 common 1/16th sizes that match with metric. 7/8 =22mm another example.
