YT-6658 rockers problem

[alsies]

Hi guys,
I have a problem - I bought a set of Yella Terra roller rockers online from VPW last week and got them a few days ago. This morning I took out the old OEM rockers and tried to fit the YT ones but the YT bolts supplied in the kit are too small and went straight in!
Before ordering the part, I checked the Yella Terra website and it stated that part no. YT-6658 is for the 3800 motors "pre-Eco from 12/90" - my car is a 1992 VP V6 and so is "pre-Eco" and also "from 12/90".
I've just emailed VPW asking them what I should do but is this a common problem?
Thanks.

Just an update - VPW got back to me this afternoon and they suggested that maybe my car had a Series 1 head installed earlier on in its life. That's possible though it must've happened within the first 3 years of the car's life as I bought the car in 1995, when it was 3 years' old.
Anyway, VPW said that they'd replace the rockers with YT-6656, which is for the Series 1 engine, if I send them the ones that I've got. Doing that in the morning.
