Finally have the body back on my 26 roadster from the paint shop and will be putting things back together this weekend. I am a little unsure which rivets to use on the trunk floor and seat back. When I took them apart, there appeared to be a mix of brazier heads and round heads. I have both on hand as well as the 'air hammer' waffle tool and bar. Question is, should I mix and match (as what was from the factory?) or stick with only rounds or only the brazier?
The car was previously repainted, but does not appear to have been altered in the past. Did a search on the previous posts about riveting and did not find conclusive results.
