Overhaul Cost? 87 300D ...

[a2t]

Mine has 280k on the clock and is still running pretty well, but its getting to be time to roll my sleeves up and do some serious work. Im trying to get an idea of what all this would cost, so I'll list some items that need attention, hopefully others will chime in and add to my list.

The car is an 87 300D, converted to run a Frybrid WVO kit 30k miles ago. New brakes all around, new h20 pump, new aux pump, serp belt, tensioner + spring, upper rad hose, recall done on the trap - new turbo!!, new fuel thermostat, new IP seals, new starter, new ignition switch, new cruise amp, new throttle linkages with METAL ball ends, fairly new master cylinder.

Easy stuff...
-Fan clutch - mine freewheels at 110C - labor = free (ie, me)
-Radiator - might as well - labor free
-lower rad hose - looks questionable - labor - free
-tstat - might as well, should of done it when I RR the water pump - labor free
-vac pump - original style - labor free, I think, if this isnt too hard!
-check chains - will need some guidance here, but assuming worst it will need new hardware - labor free I think, maybe...
-belt damper - labor free (all the other belt tensioning apparatus replaced)
-alternator - works well, but really old - labor free

Harder stuff -
-trans dripping out of front seal - definitely dont want to attempt this on my own...rebuild it or get a reman?
-suspension - its all gotta be replaced, totally worn, rear axle lots worse than front - again, labor will be paid on this item!

Anything else thats common to replace at this vintage? I take it on long trips with family, and really dont want to be stranded. Trying to decide if its time to move on to newer car, or make this 1 a life long companion.
