Definitely address the triangle while the engine is down, the seals are cheap and it only takes a few minutes.
Other thing that is easy to address while the engine is out is replacing the engine sound pad.
A close inspection of the fuel and vacuum lines, replace anything that is the least bit questionable.
If replacing the clutch, I went with the spring centered unit rather than the rubber disc style. Also check the clutch fork bearing to bushing upgrade has been done.
It is a slippery slope, many tasks become much easier when the engine is down, you want to take advantage but not break the bank.
Love my 87, happy motoring
