Cab mount bolts

Can anyone tell me what size bolts to use for the cab to frame mounts? I have a new set of wooden mounts but the bolts are long since gone. Do I use some
sort of spring or do I just tighten a nut onto it? do I need any fabric between the cab and the frame to mitigate squeaking?

as you can see, I'm going at this blind. Any pics or advice is helpful. Thanks in advance.

I didn't go stainless, but used a kit similar to this one

My goodness that is expensive. Seems like it would just be a few bolts, washers, nuts, and maybe some valve springs.

Any idea on the size of the bolts? I'd like to see if I can piece it together with Grade 8 bolts.

I use 3/8" bolts with nyloc nuts and valve springs. Washers as needed. Length of bolt is determined by block thickness at location and I compress the spring but leave some space between the coils. Doubt you need grade 8. Not too scientific, but never had one fail.

ok thanks. That is more along the lines of what I am thinking. I appreciate the insight from both of you.

I see on Macs they sell a roll of fabric/rubber material to prevent squeaking. Is this necessary? Worth it? I don't mind getting it, but if it doesn't really serve a purpose, I will pass.
