I have a solid axle TR4A that is completely disassembled for restoration. There are two holes in the trunk lid for the "TR4" and two holes for the "A". The two holes for the "A" are 4-1/8" from the right edge of the trunk, and 6-1/4" and 6-7/8" up from the bottom edge. The bottom hole for the "TR4" is 1-1/8" to the left of the bottom "A" hole (oops!) which puts the upper "TR4" hole about 3-15/16" away on center. That hole is also 8-1/8" to the left of the right edge of the trunk.
If none of the above is completely clear to you I would be happy to trace a pattern for you and mail it along before you drill. Just send a pm.
Best regards,
Brian
