Getting ready to replace flexplate

[1986nate]

So I bought my first svx a few weeks ago and just after a few days of driving developed a knocking/ticking noise and by searching through this forum was able to figure it out it was the flexplate and nothing more serious. Now I'm starting to order parts and get ready to do it and I'm wondering if it is necessary under any and what circumstances to replace the bolts or if I should just reuse the old ones. No one has really said anything about getting new ones but don't wanna have to wait another week waiting for 5 bucks in bolts.
Also I plan on doing the ball joints as one is bad and I will be taking them apart anyway in the process (plan on removing ball joints and just moving transmission back and not full removal of the transmission)- And again am wondering if it is necessary to get new bolts and nuts for the ball joints. This I've heard is recommended but for all nuts and bolts needed its over $20.
I don't want to seem like a cheap-a** just saving every little bit helps for future repairs down the road.

Any input or advice is greatly appreciated.

Thanks-Nate
