Curious if anyone has replaced the top dash on an 80. The LX450 I recently brought back from SoCal is cracked and have a replacement. Also installing with new dash a 2-din head unit, CDL switch and RX300, heater switches in the lower bezel blanks and . Will use the donor dash and a diagram from service manual as a guide to find what screws to remove. Is this pretty straight forward? Any watch outs or tips?
