I generally share the "if it aint broke, don't fix it" logic, and I've followed that advice for a lot of years on this car, but my plan here is to restore (that's the operative word, restore) the vehicle after 23 years to like-new condition for the next 23 years.
It's entirely possible that none of the suspension components is broken, but it's a sure bet that they are all worn, and that's what the restoration project aims to correct. I may end up doing some of the work myself, but if not, it will be done by my trusted indy.
@mercy485, the price you quoted for front-end work was at a shop, not DIY? That couldn't have included struts along with everything else, did it? You're figuring the rear-end will be more expensive than the front? Do others agree that the rear suspension/subframe is more expensive to R&R than the front?
It looks like the general consensus for total rebuild, front and rear, with OE parts at a shop, is in the range of $2,500 - $3,500. If the work is all done at the same time, roughly how many labor hours should that be based on? Thanks for your many interesting responses.
