I tinkered around some more in the garage. Got the other servo hacked to a continuous servo, & then installed into the Bruder D5 conversion.
Also here's the pic of the jig I made so both side are identical on the conversion

I FORGOT to reverse the + and - wires on one of the servo's, so when I plugged them in, one ran reverse, while the other ran forward. No worries, I'll reverse the polarity of one of them when I hook it to the Sabertooth.
