DVLA Inspection

[gus]

I was wondering if it is possible to the the DVLA inspection before you have IVA?

Reason is I made up my own chassis number & I want to get this checked and approved, and set the ball rolling at the DVLA.

Is there a time limit from when you first go to the dvla and have the build up inspection, to when you have IVA done and get the MAC?

I assume I just contact my local office for a info pack with all the relevant forms.

Thanks

Mark
