Thought I'd offer these up for a forum share so others can see if they prefer them over spikes. I removed them from my SDA-converted 8TL's and will not be setting them back up as RTA's.
Chime in if interested and I'll pay to ship US-48. Keep them a few weeks until someone else wants to try them and pass them on.

Re: Monitor 7A Resurrection - Advice Needed
If you are going to go the full baffle replacement route you could go with 1" MDF or maybe even HDF if you know someone who works in a cabinet shop that can get it. You could put a 1/4" chamfer on the outer edge and 1/4" rabbeted construction so that the internal volume remains the same.
I wouldn't worry about chamfering the inside edge of the baffle if you kept the baffle 3/4" and countersunk the drivers. I'd definitely do it with a 1" baffle though.
The SL2500 only came with the M7 Series II which had a different crossover from the 7C. To use the RD0-198 you have to either do the TL mod to the 7C crossover or get the Series II crossover.
PS: It is possible that the passive radiator in the 7C and Series II could have had a different tuning mass compared to the 7B and 7A, because it is based upon the midwoofer it is paired with and the enclosure volume. See if the seller has the passives too.
