these fitted really easily.
all my Lima 33s seem to have buffer beam damage. Heljan sprues are fairly cheap and the beams ca be made to fit snugly under the Lima body.

LHS is front and Heljan parts. RHS is rear and jumpers are bits of wire with a blob of glue one end and a short bit of wire glued the other end at 90deg.
Multiple working sockets are a small bit of sprue with a bit of tube glued on the end (little oversized)

Lima models all have buffers again!!
