Just got another goody today so I thought I would share
The Triumph D-type Overdrive adapter Woo Woo Woo lol...
I can also confirm that it fits without issue. Remember that this Overdrive came from a Volvo 1800 not a Triumph Spitfire. So for anyone who is wondering if this can really be done I am here to tell you it absolutely can. Quick recap for those that are unfamiliar and wondering why the heck would I get a Volvo OD instead of a Triumph. The main reason for using the Volvo OD is for the taller gearing. Triumph Spitfire/GT6 overdrives only came with a top of .25% reduction this Volvo bad boy has a reduction of .32%. This is a significant gearing difference and will drop RPM's quite a bit and in theory increase fuel economy.
Soon enough I will have the transmission out for a look over and then the full rebuild will begin
GH..
