I've been wanting one for awhule, but I'm sure shipping would probably be crazy. I'm in Nj. I have an 03. Is it heavy?
Not really, maybe a couple pounds. Its a nice strong composite plastic. I just mounted a cheap 8" $20 sub off amazon in it. Get me a zipcode and I could get you a shipping quote.

Well replaced ac compressor,new hi/low line BUT I had to cut the drier off ,the theads was rusted together I cut little of the evaporator line that the o-ring sits on DamDam so I need to pull the dash to replace it. Now the small line to condenser won't loosen to replace orfice tub the line is twisting so I will get a new line. AND that PB blaster is awsome

After I got off work noticed my brakes were a lil squishy, thought I blew a wheel cylinder but turns out it was the brake proportioning valves front equalizer decided to squirt fluid all over the engine bay and not to my brakes. So I drove 35 miles in stop and go traffic in 100+ degree heat using only my transmission and my e brake... talk about stressful! Once I got home I got in my sons car and made a Summit run to pick up another, got it in and bled, I’ll take the bad one tomorrow and hopefully get it credited for warrantee...

MPFI Spider Conversion Complete

I finally got it done and I am thrilled with the outcome. I did a full write up on my Project 99 Yukon build thread.

Before: (the coolant is my spillage during the teardown so no worries!)

MPFI Installed and ready to reverse the process.
