I was installing a 8?s 740 Volvo IC on my GTU..when I noticed that I would need to eather use a longer IC or a shorter radiator to squize the IC pipe trough the sides. Then I just snaped...Just use the DAM Volvo radiator. On my app... my radiator fill cap is on the watter pump return pipe..so its perfect since the Volvo rad doen't have one. Maybe welding a rad fill cap on the volvol rad is all you need to work on the TGPs. Just a thought.
