They do fit. The front is identical, I ran my RD07a wheels on my RD04 when they were getting done so are directly interchangeable. The RD04/07/07a have the same swinging arm.
The rear rim is slightly smaller in width so would run a 130 tyre normally but I've had a 150 on them. A 140, which is the normal tyre for RD07a would fit too. Early 07's ran a 130. I'll check on postage but would be looking for £150 for the pair + postage
