Just seen this post!
I have a 1987 504 pick up with a 2lt TI motor going thru to a BA7/5 gearbox with a TI diff.centre ," it came to Australia as a diesel and I brought it in Canberra as above!! Since then, I'll used a 505 S/W rear axels and drum brakes, 604 front brakes with 504 hubs. running TI rims . Been using it as my daily driver for 5 years now and runs very well. It will take any load and then some!
