Morning all - joined last nite. Recommended by Brosky who has a wonderful site with lots of pics that really help seeing details. I have a 73 TR, today the muffler and rear pipes go and the I will pull the differential. Leaking pinion seal is bugging me. Neat site here - so 1st question heat in the cockpit passenger side. Thinking its the old muffler restricting flow and building extra heat - but seems its a common issue from others. What to do? I have put in insulation under carpet - but in SW florida sitting in traffic on a summer day - wife says TOO HOT! May need more insulation but in the engine bay on firewall? Thanks in advance.
