Please school me on sbp rally wheels...

All small bolt rallyes are the same size...14x5.5". All will fit your car. As for the center caps, the correct caps for 1970 would be the cone style with light argent paint. Any of the small bolt centers will fit though, the difference being the dark argent paint on the 71 and up cone style, and the late 72-74 acorn style. IMO, the cone style is the better looking cap, and I'm a big fan of correctness, so I would go light argent. The trim rings should be for a 5.5" rim and sit right down on the inside lip of the rim, where the rim center meets the rim. A trim ring for a wider wheel will not snap onto the lip of the rim, and a 5" trim ring will be just shy of the inside lip, although they will work. I'm not sure of the correct finish, but most likely it will be polished so when it meets the inside lip, it makes the "D" shaped holes in the rim look circular. A cool look IMO!!! Hope this helps, Geof
