Hello, I recently purchased a 1989 International s3700 bus with a ward body and the 7.3 idi engine and at545 transmission. The thing was a bit of a basket case when I bought it but i am finally getting things smoothed out. The trouble i am having is the best place to locate some of the parts for this chassis. When i bought the bus, the front pump seal on the trans was leaking. I have since replaced it but during the process I damaged the dipstick tube

and the only replacement i can find online is one that says it is universal for a at545 and is kind of expensive. Also, when I bought the bus, the parking brake cable was cut due to being froze up and I haven't had any luck locating a replacement. Is there any good places to source chassis parts online or am I going to need to go to the international dealership directly to find these parts? The nearest International dealer is several hours away. Thanks for the help!
