DOES ANYONE HAVE A CLOSE RATIO GEAR SET FOR A 63A.I HAVE ONE FOR AN A SERIES ENGINE AND REQUIRE 3RD CLOSER TO 2ND.

Close ratio gear sets can be made for anything, I got a close ratio gear set for a 60l box years ago, but a close ratio set for the 63a box would have to be sourced from probably Japan or USA. Try EBay in these countries for parts.
I recommend you call somebody like Stewart Wilkins at SWR or maybe email & ask about your options, as well. Most gear sets will move 1st & 2nd closer to 3rd, but there was a gear set for the 60a 4 speed that lowered 3rd gear, but was for rallying only. I dont know anymore about that gear set than what I've told you, sorry , I only saw that particular Sports Option catalogue once, & that was in the early 90's. It was the one for the B310 Sunny, which had all the parts numbers for A14's & A15's. What car is this gear box in?

could the internals of a 63a from a l series SSS dog leg 5 speed work?

they have a nice 2nd to 3rd unlike the stumpy boxes.

im starting to fall in love with mu dogleg. i might give it some loving like a dog gives a human leg soon enough
