rcreweread Posted April 23, 2021 Report Share Posted April 23, 2021 Guy - The threads are UNF and I'm pretty sure they are 1/4", but if not then they will be 5/16th cheers Rich Quote Link to post Share on other sites
OldBob Posted April 23, 2021 Report Share Posted April 23, 2021 (edited) 5/16" UNF from memory, but if you are measuring them as 6mm then as Richard says maybe they are 1/4" - but definitely UNF Bob Edited April 23, 2021 by OldBob correction Quote Link to post Share on other sites
Guy Vinall Posted April 25, 2021 Author Report Share Posted April 25, 2021 Thank you all. I have purchased some 1/4 & 5/16 UNF slightly extended bolts & will be fitting some small spacers (6-8mm) just to slightly lift Pauls brackets. Quote Link to post Share on other sites
ed_h Posted April 25, 2021 Report Share Posted April 25, 2021 TR6 cars came with spacers under the seat tracks (at least my 74 did). Factory spacers on the left, more serious ones on the right. Ed Quote Link to post Share on other sites
tr6tuga Posted April 29, 2021 Report Share Posted April 29, 2021 Just what I was looking for can I have aprix measures ? thankyou Quote Link to post Share on other sites
ed_h Posted April 29, 2021 Report Share Posted April 29, 2021 The original spacers were about 1/4" high, with an ID a little bigger than necessary to fit over a 1/4" bolt. Ed Quote Link to post Share on other sites

AarhusTr6 Posted May 3, 2021 Report Share Posted May 3, 2021 Hi So did these spacers then lift the frame up, a bit from the carpet to give a mroe free movement? is that right? Richard Quote Link to post Share on other sites

Richard I think it was less about free movement than getting a solid mount of the seat frame. Ed Quote Link to post Share on other sites
Kenrow Posted May 3, 2021 Report Share Posted May 3, 2021 Original screws were 1/4 inch UNF x 1 inch. If you add thicker spacers you may need to adjust accordingly. Quote Link to post Share on other sites

ed_h Posted May 4, 2021 Report Share Posted May 4, 2021 Richard-- I can't easily get at them to measure, but I know I made them a little thicker than stock--around 5/16, I think. ID a little over 1/4", OD not critical, but it looks like about 3/4". Ed Quote Link to post Share on other sites
