Bilstein Rear 5125 Installation--New Bolts?

Hi. I've lurked here a long time while looking for a 1st Gen. I finally got one: 2000 ExCab TRD 3.4 auto in Imperial Jade Mica. One owner. Brand new 10-31 Destinations so they are there to stay a while.

I'm a member of some other forums because I have 1989, 2000 and 2008 4Runners and three teenagers.

I just ordered a Bilstein kit from Down South. I know to get the front bushing set# TTL-142467 from Toytec. I'd like to replace the nuts and bolts and washers on the lower eyes and the ones on the rear. I've searched extensively and can't figure out what most people do. It looks like its a
M12-1.75 bolt. Do most people just go to Tractor Supply and get the grade 8 bolts?

This is the kit. Can't wait:

I think most people just re-use their bolts.. Unless they're damaged in some way.

If you just want to replace them for your peace of mind, go ahead and source the correct ones from your fastener store of choice, mine is generally either Lowe's or Advance Auto

 

My local Fastnal has lots of good metric items.

 

I just reused the originals, they were in decent shape.
