it sounds to me youre using a short footed adapter with a tall style crossmember.
the stock adapter for the 241 has a short foot like this. probably what you have.
the short foot adapter goes with the "W" or "S" shaped crossmember. a 205 shown here, but it is a 1985+ crossmember.
this is the tall th350/208 adapter. 208/241 are directly interchangeable. goes with the flat style crossmember. seen on
ebay <click that.
all shifters from 1983 or so and newer for a 208 and 241 are the same. just find one of those. they came in k5s and subs k10 ans k20, k10 and k20 pickups as well.
