There are two types of headlining for the Toledo depending on whether it’s a 2 door (part no 721429) or 4 door (617429).
The 4 door item is article the same as a Triumph Dolomite one, it’s the same part number listed in the Dolomite parts book.
The 2 door item differs slightly as the top part of the B-post is sewn to the headlining, rather than being a separate piece.
Rear – HB1138 – 1/2″ x 4.75″
Front – HB1140 – 1/2″ x 5″
Toledo Parts book:
These are the original bolts removed from the car which measure 4.75″ and 5″ – since we know from the forum post that HB1138 is 4.75″ HB1140 must be 5″.
This differs somewhat from the Dolomite ones, HB1148 is 6″.
