well they have to pull everything with the frame machine and replace everything. But where your parts came to 1022 and theres were 1800. You might have just been using like certifit parts or some off brand and they are using actual oem parts from toyota for GUARANTEED fitment with no extra work. Its easy for them and they dont have to pay the extra 700$ for the parts so they are gonna go with the oem fitment. Thats why the price is different sometimes its a bitch to get certifit or other fenders/rad support to line up b.c there not to the exact specs but pretty damn close
