Thermostat housing
 

Ok so i have a little problem with my 83" 380sl.. I have been needing to change out the thermostat on my sl , so i took advantage of the nice weather.

I was taking off the bolts very carefully do to the old age of my car, when my nightmare started .. The bolts snapped two of the three from the thermostat housing, i had to drilled them out and let me tell you that was fun.

Does any one know the replacement bolt size? Also where i can find them? Thanks in advance guys

I think they are 6mm thread size, the pitch might be 1.50. It's been a while since I did one of those myself. I'm sure some of the others will know exactly.

The local home supply center usually has a good selection of metric bolts and washers.
