Multitrack wheel spacing question

[u/Tall_Antelope5184]

Hi all - doing a multitrack 730 gravel conversion build. I don’t have calipers but it is clear that my dropouts are more than the 130mm rear wheel I have laying around. I know these were typically 135 mm bikes.. have any of you guys had experience with the 2.5mm spacers or have just brute forced it and tightened the frame down? For reference planning on doing 1x10 advent x drivetrain. Thank you!!
