Thanks guys! Yeah I did alot of questionings at the retrofitsource.com and the guy reassured me that using the 50w ballasts with 50w hid bulbs won't give as much heat as compared to using a 50w ballasts with a 35w hid bulbs which overpowers them which creates alot of those heat issues and shorten the lifespan of the bulbs too. Plus the 50w hid bulbs glass capsule is made thicker from the 35w ones which suppose to help out with the heat problem. I think you are referring to the Mini H1, which don't have the 50W option when you make an order, plus the back reflector bowl is so much smaller as well, which makes it not compatible with the 50W setup. As for the foglights. here's a couple of pics I did.
Cut a hole big enough to fit the foglights.
And I just use the leftover headlight sealant to seal all around the edges and then I just use the stock foglights mounting brackets to mount the whole thing. I used a little bit of JB Weld to secure the Blazers mounting holes to the oem brackets and it seems to work well. Sorry I didn't take any pics of the completed mounting of the fogs as it was getting really late and we hurried to get it all done.
