Im on the road no where near my car or parts piles.
You can use a small screwdriver, chunk of solid wire, or a nail to see how long they need to be, just get a bolt that is slightly shorter than how deep the nail goes into the cover and block. If the hole is not very deep (dont remember many like that on the 200) use a washer or two to get the exact length since you can only buy bolts in 1/4 or 1/2" steps at most hardware stores.
From memory there are 2 length bolts in the front of the timing cover (not counting the 2 sizes and lengths that come from the oil pan). I think they are 1/4-20 which are very common. I seem to remember it was obvious which ones were short and which were long. The factory bolts had a 3/8 head, common replacements would have 7/16 heads. Heads shouldnt be critical since none of them are behind the pulley. I think AC equipped cars had a extra timing gauge thing that went under 2 of the bolts but I dont remember having any issues removing it. T stat I think were 5/16-18 (maybe 3/8-16). Standard grade 2 or grade 5 will be fine, avoid grade 8 because they hard to drill out if you ever brake them.
