Hi Brad,
The difference between TR4 & TR4A tonneaus is the former has 16 versus
8 'lift-the-dot' fasteners around the back. Both have normal round
snaps for the dash area that are identical to the door tonneau snaps.
Those front round snaps are a real pain to operate in that tight
awkward windshield area with a nice tight tonneau. I would prefer the
TR6 solution of a bigger hole (with chrome ring) and the simpler post
(not a lift-a-dot style). With a taught tonneau, which is what you
want, the simple TR6 style is a finger and knuckle saver. Even if you
hook the original round snaps on your dash first it's then a bear to
get the lift-the-dot snaps hooked up on the back. Finally with the
TR6, the factory came up with a real nice solution for the front
fasteners, ie; big hole/simple post. I would definitely not use
lift-the-dots on front. IMO the snaps are better, but the TR6
hole/posts design easiest to operate.
Regards,
Carl
'63 TR4 since '74

I'm trying to find out what if any differences there are between the
TR4 and TR4A tonneau covers.
My 63 came with a black tonneau that had been reworked to fit around
the roll bar and since I'm taking the roll bar out I need to use a
different tonneau cover. The fasteners for the dash were the
Lift-A-Dot style of fasteners as are the ones around the rear cockpit
aluminum trip strips. The doors had the round snaps installed which I
believe is typical for all tonneau covers.
At some time in the past I acquired a nice original (at least I think
it is original) white tonneau. This particular tonneau has the push
snaps like those used on the doors although it has the Lift-A-Dot
style fasteners for around the rear cockpit trim.
So the question is are the TR4 and TR4A tonneau covers different? I
would think a 63 TR4 would use the Lift-A-Dot style of fasteners on
the dash for the tonneau. I base that statement on the fact that my
64 Spitfire used the Lift-A-Dot style for the dash as well so I would
think a 63 TR4 would be the same.
I would prefer the Lift-A-Dot fasteners so I'm also wondering if I can
replace the round snaps with Lift-A-Dot fasteners without ruining the
tonneau.
Thanks!
Brad
